This security update resolves one publicly disclosed vulnerability and three privately reported vulnerabilities in Microsoft Lync. The most severe vulnerabilities could allow remote code execution if a user views shared content that contains specially crafted TrueType fonts.
This security update is rated Important for Microsoft Lync 2010, Microsoft Lync 2010 Attendee, Microsoft Lync 2010 Attendant (32-bit), and Microsoft Lync 2010 Attendant (64-bit). For more information, see the subsection, Affected and Non-Affected Software, in this section.
The security update addresses the vulnerabilities by correcting how specially crafted True Type Font files are handled, correcting the manner in which Microsoft Lync loads external libraries, and modifying the way that SafeHTML function sanitizes HTML content. For more information about the vulnerabilities, see the Frequently Asked Questions (FAQ) subsection for the specific vulnerability entry under the next section, Vulnerability Information.

Once in a while I find a new tool or other goodie that immediately draws my attention and is flagged "very useful" within a few seconds. The Lync Topology Info XML powershell script from Chris Cook is one of these examples.
This powershell script will generate an excel sheet and visio sheet based on the topology builder XML. Great for inventory or for reference and since it's free, there is no reason for not using it. If I would have seen it earlier, I would definitly spoke about it on my Community Day session yesterday.
Microsoft just released the Lync for iPad client version 1.5 on iTunes, and a great new feature has been added.
Your Lync servers need to be patched with CU6 (June 2012), and then your iPad users will be able to see the PowerPoint presentations shared during a Lync Conference. This is how it looks like:
As said, this only works when:
This is one excellent tool that will prove to be very valuable in troubleshooting scenario's.
The Lync Firewall Rules Viewer is a Windows 7 application that visually illustrates the network traffic between any pair of server or client Lync endpoints. When the administrator selects a source endpoint in the left pane, the list of possible destination endpoints this source can communicate with is shown in the right pane (See figures below).
On a 64-bit system I got the following error when opening the application:
I did exactly that but still it didn't work. I only get it working on a 32-bit system, what's your experience? I'll contact the author for more information

Most of you will be well aware that Microsoft has a Compatible Devices Program for Lync 2010, which is updated regulary. On this list you'll find all devices that were successfully tested and working with Lync 2010.
Because of the different underlying architecture of the Mac OS system, this list is not applicable for Lync for Mac 2011.
While it is not an official list, Tom Laciano created a Lync for Mac 2011 Devices blog post on Technet where all community verified devices (working or not working) are documented.
Microsoft published the following documents describing DirectX acceleration for Video a little while ago.
Now I am wondering whether this would lower the Hardware Requirements for HD video in Lync?
The Current Hardware Requirements for VGA & HD Quality video are the following: Video: Dual Core 1.9 GHz processor or the latest version for VGA; Quad Core 2.0 GHz or the latest version for high definition
More info on the Hardware Requirements here : http://technet.microsoft.com/en-us/library/gg412781
DirectX® Video Acceleration Specification for Windows Media Video® v8, v9 and vA Decoding (Including SMPTE 421M "VC-1")
Defines extensions to DirectX Video Acceleration (DXVA) to support decoding of Windows Media Video.
Note : VC-1 is actually the Video Codec used by RTVideo
DirectX Video Acceleration (DXVA) Specification for H.264/MPEG-4 Scalable Video Coding (SVC) Off-Host VLD Mode Decoding
This document is the specification for support of Scalable Video Coding (SVC) according to the H.264/MPEG-4 video coding standard within the Microsoft Windows DirectX Video Acceleration (DXVA) API/DDI context.
Note : H.264 SVC is the Video Codec used by Lync 2013
The Presence Bootstrapping Tool for Lync Server 2010 sets default presence policies for identities that have never previously signed into a Lync Server client. This utility is intended to be run once for users of some qualified client applications that are not released by Microsoft (for example, Polycom KIRK). Any qualified partner solution that requires use of this tool will explicitly direct you to it. Use this tool only if directed by a qualified partner solution provider or by documentation for the users of that solution. For further information please see Knowledge Base article 2737277.
Presence Bootstrapping Tool for Lync Server 2010 must be set up and configured as a Lync trusted application before running. The Lync trusted application ID must be set in PresenceBootstrapper.exe.config.
See http://msdn.microsoft.com/en-us/library/hh347354.aspx for information on configuring a trusted application. Note that optional steps pertaining to Active Directory Contact Objects may be ignored.
The utility can be run on a single identity or multiple identities. Examples:
As many of you might already know, Microsoft released Windows Server 2012 this week.
Some great information can be found here:
Without any doubt, this is the best Windows Server edition ever released with tons of new features like Hyper-V 3.0 and a much improved server manager. If you want to try it yourself, visit the Windows Server 2012 Trial page and download yourself a free trial copy.
But how does Windows 2012 go with our much beloved UC products Lync Server & Exchange Server?
Please find an overview below
Lync Server 2010
To know which server edition of Windows is supported for use with Lync Server 2010, we take a look at the Server and Tools Operating System Support page in the Lync technet library. This page was not updated for Windows Server 2012 which means that right now it is not supported to install Lync Server 2010 on Windows Server 2012.
At the moment it is not known if Microsoft will release an update for Lync Server 2010 which will enable support for Windows Server 2012. Please keep in mind that Lync Server 2010 was not designed to work on a newer release of Windows Server and it will depend on technical limitations if Microsoft will release such an update.
Current Conclusion: not supported
Lync Server 2013 (Public Preview)
The Lync Server 2013 Public Preview technet library has the same Server and Tools Operating System Support page, which states that Windows Server 2012 is supported.
Lync Client 2010
On the Lync 2010 System Requirements page we find no mention on Windows Server 2012, which means it is currently not officially supported.
Since Windows 8 and Windows Server 2012 are build with backwards compatibility in mind, my personal opinion is that Microsoft will add official support it later on. This official support can be added with either a Cumulative Update or just an update to the system requirements page if they found no issues.
Current Conclusion: not yet officially supported
Lync Client 2013 Public Preview
The Lync Client 2013 requirements page states that Windows 8 and Windows 7 are supported; and since Windows Server 2012 is the server edition of Windows 8, we can conclude it is supported.
Conclusion : supported
Exchange Server 2010
Same as with Lync Server 2010, the System Requirements page for Exchange server 2010 was not yet updated and Microsoft did not release a statement regarding Windows Server 2012 support.
Important to know is that some Technet pages already talk about Exchange 2010 SP3, but it is unknown if Windows Server 2012 support is one of its features.
*update* : blog post from msexchange team stating that it currently is not supported but support coming in a future update! (My bet: SP3)
*update2* : Exchange SP3 was announced by the MS Exchange team. It will be available Q1 in 2013 and will support Windows Server 2012.
Current Conclusion: supported with SP3, to be released Q1/2013
Exchange Server 2013 Public Preview
The Exchange Server 2013 Public Preview System Requirements page mentions support for Windows Server 2012.
Windows Server 2012 includes Hyper-V 3.0 with a lot of new exciting features. So what about support for virtualized Lync and Exchange environments?
Understanding Exchange 2010 Virtualization states that only Windows 2008 and Windows 2008 R2 Hyper-V are supported hypervisors for Exchange 2010.
Virtualization Support for Lync Server 2010 states that Microsoft Hyper-V is a supported hypervisor, not defining a specific version. If we look further and check he Server Virtualization in Lync Server 2010 document , we find that only Hyper-V 2.0 (Windows 2008 R2) with a specific hotfix is validated to work. Hyper-V 1.0 (Windows Server 2008) is not supported at all because it does not have specific features required for real-time communication workloads.
Since Hyper-V 3.0 is a much improved version of version 2.0 and includes the same and more features, it is just a matter of time before Microsoft will validate Hyper-V 3.0 as a supported hypervisor platform for Lync/Exchange workloads. At this time, the official documentation does not mention anything about it, so....
Current Conclusion: not yet supported
What does "Not Officially Supported" mean?
Not officially supported means that Microsoft did not validate the product to work in these specific conditions and that Microsoft can not guarantee that the software will work as expected.
If you do use the software in an unsupported scenario and have issues while doing so, you can call Microsoft Support for help but this will be "Best Effort". Microsoft will not take any responsibility what so ever in an unsupported scenario.
Today the Microsoft Lync Team announced through Twitter that the Lync Push Notification Server will be down for service maintenance until the 8th of October 2012.
"NOTICE: Push Notification Service is down until Monday Oct 8 2012 due to service upgrades and maintenance. Spread the word! "
The Push notification service is used by Lync Server to send Push messages to Windows Phone and iOS devices. As long as the service is down, iOS and Windows Phone will not receive any Push notifications.
While you can use Lync as a complete softphone solution, many of my customers still have users who prefer to have a hard phone on their desk. For best user experience, click-to-call is the most obvious feature they are using.
If you look at the Lync solution ,Lync Aries devices and the USB better-together feature are the way to go to have integration between a PC and a desk phone. Many of my users are currently using this feature and are very happy with it.
So what options do you have if you decided on investing in SNOM phones instead of the Aries phones? So far none.... but this changes now!
A new call-via-phone app has been published lately to facilitate click-to-call with SNOM phones on the latest Apollo firmware. The bad news is that it's not yet clear if this will be a free or commercial application (it has a 30 day limitation but linked to a freeware section), and this first release will probably not be production-ready.
A new Tools menu-item has been added to configure the application
End-user experience for click to call
As far as I know, similar functionality is not (yet) available for the Aries phones because they do not have an API built in to trigger the remote call..... Maybe a good idea for future firmware releases, Microsoft?
- There is a 64-bit version available right now
- The author is planning to implement it at a customer so the stability of the app might be very good.
The new Lync Cumulative Update has been released.
Updates for Lync Server 2010
Lync Front-End Server
Description of the cumulative update package for Lync 2010: October 2012
Description of the cumulative update for the Lync 2010 Attendee - Administrator level installation: October 2012
Description of the cumulative update for the Lync 2010 Attendee - User level installation: October 2012
There is an update to the Lync Mobile client for Windows Phone. Finally this update displays Mobile Phone numbers on the Contact Cards (this was something I really missed)
Additionally : If you were having issues joining an online meeting with Lync Mobile on WP7 then this is your solution :)
This cumulative update fixes the following issues:
History.... I have to admit it was not one of my favorite classes in school. Right now, my work (IT) is completely focused on the future: new features, faster services and increased productivity. Nevertheless knowing the roots of all things we consider as "usual" right now, might give you a broader view on how great these systems actually are...
Therefore, I decided to create an historical overview of Microsoft's products and services related to Unified Communications. As you will see, Unified Communication did not fly in out of the blue with OCS 2007. It was lingering and growing in previous and other products released by the company, many years before.
Starting from LCS, I'll limit myself to the most important changes in the product line. I believe we then reached the point where more information can be easily found on the internet.
Let's get started... now!
Disclaimer: this is an unofficial historical overview based on my knowledge and information found on the "worldwide web". It's not proven to be 100% accurate and might be missing some information. If you have something to add, please do not hesitate to contact me through twitter (@rnauwelaers).We're all here to learn, aren't we?
Once upon a time.... there was E-mail (1988)
During the 90's, companies (including Microsoft) started to understand the real importance of networks and the internet from a business perspective. Things started as "workgroup-mail" and quickly evoluated to internet-based e-mail.
Microsoft Mail (1988)
The first Microsoft Mail product was launched in 1988 and build upon AppleTalks networks and the Macintosh platform (yes, you've read that correctly). Later on, an MS-DOS client was added for PCs on AppleTalk networks. The Macintosh mail product was sold to another company and as you can expect, no longer lives on.
Later on (in 1991), Microsoft created a "new" Microsoft Mail product for PC Networks. The product came again from an acquisition from Network Courrier and clients were developed for MS-DOS and Windows. The Windows client received the original name "Windows for Workgroups Mail".

A stripped-down version of the PC-based server, Microsoft Mail for PC Networks, was included in Windows 95 and Windows NT 4.0. The last version of Microsoft Mail was 3.5
Exchange Server (1996)
The first Exchange version was announced in April 1996 and released on 11th June 1996 with build number 4.0.837 (see all build numbers and release dates here). It was announced as an upgrade for Microsoft Mail 3.5.
Exchange 4.0 was completely based on X.400, which at that time was the most common used mail exchange protocol. It's only at a later time that SMTP was preferred and for backwards compatibility X.400 lived on in Exchange until around the year 2006.
By default Exchange 4.0 could not connect to different the Internet or other directory servers. There were optional components for that, that could be added using the installation disk or through a download.
Exchange 5.0 was released in March 1997, building on the Exchange 4.0 Legacy

Exchange server 5.0 also introduced Outlook Web Access, a web based email client.

Say hello to Chat Rooms (1996)
If we go back in time and look at the first chat/IM related products that Microsoft provided, we can consolidate this in chat rooms. Chat rooms were introduced in hosting-provider solutions like Microsoft Commercial Internet System in the dark ages of internet communication . During these dark ages, information availability was not as bright as today and most documentation vanished over time... As a result information is rare, but severa lookups on our favorite search engine GoogleBing provided me with a complete set of MCIS documentation and some screenshots. The product was released around mid 90's, probably around 1995-1996.
Some screenhots to"showcase" it's look 'n feel (do you even remember Windows 95 look 'n feel ?):
As you can see this is really back to basics. (If you are a"less-is-more" fan, I suggest you to have a look at these and ask your boss to run a proof of concept in a virtual machine ).
From a technical
perspective, the underlying protocol used was Internet Relay
Exchange Server on Steroïds (1997)
While Exchange Server was originally just a email system, Microsoft understood that networking could be used for a lot more than just e-mail communication. At that time, Exchange Server features were expanded with some chat room capabilities.
Microsoft Exchange Chat Server
With the release of Exchange Server 5.5 Microsoft introduced the Exchange Chat Server.
Just like the previous Chat server software, the Exchange chat server supported the IRC protocol together with a Microsoft proprietary protocol "Microsoft Internet Chat (MIC)". MIC was later phased out in favor of IRC. Microsoft also released their own IRC chat client "Microsoft Comic Chat" in 1996 which was delivered together with Internet Explorer 3.0.

The Exchange Chat Service was delivered as a service for the "Internet Service Manager", the early version of what later would become IIS server. I found a great article on how to Configure Exchange Chat Server here.

Exchange Server 2000: Chat, IM and Netmeeting Conferencing (2000)
The next version of Exchange Server was Exchange 2000 and was the first version to include support for Active Directory, first released on Windows 2000 Server.
Regarding communications, Microsoft added a new Instant Messaging Server, improved the existing Chat server and even created a "Microsoft Exchange Conferencing Server 2000" SKU. Microsoft Exchange 2000 Conferencing Server was designed for complete data, voice, and video conferencing. Service Pack 1 even added a web scheduler so users without the Outlook 2000 client could schedule a new conferences.
From a technical point of view, Microsoft Exchange 2000 Conferencing Server employed two mechanisms to provide the audio/video stream to video conferences:
In 2002 Microsoft announced the MSN Messenger Connect Service, allowing organizations to link their Exchange IM capabilities to the MSN Network (at that time 75 million users) and have extensive archiving options.
You have to admit that a few things sound familiar:

Live Communication Server 2003: the introduction of SIP
As instant messaging and presence products became more popular, Microsoft took the instant messaging engine out of Exchange 2000 and turned it into a stand-alone product, Live Communications Server 2003 which was released on 29 December 2003. Windows Messenger 5.0 was used as the client and the following protocols where supported
As you can see this is the first version of Microsoft's communication software that introduced support for SIP and made it the default protocol. The SIMPLE extensions for SIP were used to support presence.
With the installation of LCS, the Active Directory schema had to be extended with specific LCS attributes.

Live Communications Server 2005
Compared to LCS 2003, Microsoft added the following features:
With the release of LCS 2005, Microsoft also introduced the new Communicator 2005 client while still supporting Windows Messenger.
Live Communications Server 2005 SP1 - Telephony Integration
LCS SP1 was the first version that supported telephony integration through Remote Call Control. Remote call control linked the telephony system to LCS and enabled LCS to receive telephony presence information. This allowed communicator to automatically set the user presence state to "in a call" during a phone call on the PBX phone. RCC was only supported with the Communicator client, not with Windows Messenger.
Live Communications Server 2005 Service Pack 1 (SP1) also added the following features:
Exchange 2007 : Unified Messaging
Unified Messaging combines voice messaging, fax, and e-mail messaging into one store, accessible from a telephone and a computer. Exchange 2007 Unified Messaging integrates Exchange Server with telephony networks and brings the Unified Messaging features to the core of Exchange Server.
Unified Messaging in Exchange 2007 gives users features such as:
Office Communications Server 2007 : Multiple Point Of Presence & Enterprise Voice
OCS 2007 introduced the concept of Multiple Point of Presence. A point of presence is a client that explicitly provides presence information on behalf of a user (presentity). In MPOP, the presentity is allowed to log in from a multitude of endpoints and provide presence information to the server. The server will aggregate this presence information and provide all ‘watchers’ a unified view of the presentities presence. MPOP and the server side aggregation (also called the aggregation script) are central to providing the right user experience.
Enterprise Voice is Microsoft's software-powered VoIP solution and was first added in OCS 2007. Together with IM, conferencing, audio/video features, and full integration with Outlook and Exchange Unified Messaging, Enterprise Voice enables Communications Server users to choose the most appropriate way to communicate with colleagues throughout the enterprise. From their PCs, users can place a call by clicking an Outlook or Communicator contact.
Office Communications Server 2007 R2 : additional voice Features
OCS 2007 R2 was released in October 2008, only a year after the initial release of OCS. This release was focused on delivering more voice-related features, enabling OCS 2007 R2 to be a PBX replacement in specific user cases.
If you don't know what followed after OCS 2007 R2, I would recommend you to read our website a bit more
That being said, I think it's time to snap my fingers and return back to present time.

I recently got the question on what CAL is required if you deploy Lync Enterprise Voice and you have the PLUS CAL for your users escalating to multi-party audio call but don’t have the ENT CAL for everyone.
Can users with STD + PLUS CAL conduct Ad-Hoc Audio Conferences, users do this when having a Audio/Telephone conversation and join in other Lync users or Phone Numbers.
While this may be a trivial question this Licensing is very complex across the Microsoft Portfolio and checking this information is important because this is something that potentially may have a huge impact on pricing for Lync Enterprise Voice
First some explanation about the Client Access Licenses
Client Access Licenses (CAL)
While Audio Conferences (Ad-Hoc & Scheduled) are technically Conferencing because the MCU is involved, me as a technical person would say that ENT CAL would be required.
Now luckily for us Microsoft included the Ad-Hoc Conferencing Capability for Audio into the PLUS CAL
And on the other hand if you only have an ENT CAL you can both do Ad-Hoc & Scheduled Audio Conferencing
This is a very good to know when competing with other UC solutions!
Today Microsoft released new hotfixes and updates for Lync 2010. Previous update was CU7 released in October 2012.

This cumulative update improves the reliability, stability, and performance of the Lync 2010 Attendee - Administrator level installation.
During installation of the first Lync Server in a greenfield environment we ran into the following issue.
The Local Installer was failing with a rather strange Error Message : “AccountDomainAdminsSid" does not correspond to a unique object in Active Directory. If you read that correctly it looks like the SID of DomainAdmins Group in AD is not unique, that is absolutely not possible because that is blocked by the Directory Service if someone would even try to do change or add SID’s manually. So what could be wrong here?
The specific customer where we ran into this issue has a very locked down Active Directory. So we executed Grant-CsSetupPermissions and Grant-CsOUPermissions for “Computer” and “User” on the required OU’s.
If we look at the requirements on Technet we find the following requirements for Deploy.exe and Bootstrapper.exe: Member of the Local Administrators group on the computer from which the executable is run. Member of Domain Users group to read information in AD DS
So we need Read Access to Active Directory! This is a very vague requirement and that requirement is satisfied although we don’t have access to all of AD’s Containers…
As it turns out we don’t have Access to the Container where the Domain Admins Group resides, so we cannot find the “Domain Admins” Group or see what Members are in there.
Trying to open the Properties of the Domain Admins group gives problems (Directory Object Not Found)
Make sure the Installation account has Read Access to the Domain Admins Group. As a compromise not to break security in the Locked Down AD we have configured Read Access for the RTCUniversalServerAdmins on the Container and child objects where the Domain Admins reside. After that change we were able to successfully deploy the Lync Server.
Why the Local installer needs access to the Domain Admins group is that the setup process must be able to read the Domain Admins SID to grant the Domain Admins permissions to DCOM registry keys.
The Lync client mysteriously prompts for Network Credentials, this had never happened and Proxy Server exceptions had been configured for all required URLs that Lync uses to connect to the Lync Server and Exchange Server.
After some investigation the popup only appears on Lync 2010 clients that have been updated to the latest cumulative update.
Lync Version 4.0.7577.4384 (No Authentication Popup)
Description of the cumulative update package for Lync 2010: April 2013
Lync Version 4.0.7577.4398 (Authentication prompt)
Description of the cumulative update package for Lync 2010: July 2013
Looking at the Support article shows there has been some updates to the Lync Client and some of the proxy authentication options
However this is unrelated to what the customer is experiencing, the popup is shown during Lync Signin process.
Using Fiddler we actually see a request going to the email domain which is something similar to this : email.contoso.com
If you know the process Lync uses to discover Exchange Web Services this would make sense, however we see no Authentication prompts for autodiscover.email.contoso.com which is the next URL that is tried in the Exchange Autodiscover process.
Why is the behavior different for both URLs?
email.contoso.com has the proxy authentication problem
autodiscover.email.contoso.com does not have the proxy authentication problem.
*.contoso.com has been configured as exceptions in the Proxy Configuration for Internet Explorer so it should have the same effect on both URLs
Doing further investigation shows that email.contoso.com does not resolve to an IP Address but autodiscover.email.contoso.com does resolve to an IP Address. So this makes me conclude that whenever there is no resolving of the URL it is forwarded to the Proxy and then Authentication must be performed.
Configuring email.constoso.com to a valid IP in the HOSTS file on the Client Machine proves my conclusion and the Client no longer prompts for authentication.
I wonder in how many organizations that the email domain resolves to an IP Address?
In my oppinion the Exchange Autodiscover process is broken in Lync because it also ignores to check the Service Connection Point (SCP) in Active Directory like Outlook does and in most cases the customers have to make changes to either DNS or Certificates on Exchange when adding Lync to their application stack.
Make sure you understand the autodiscover process Lync uses for Exchange Web Services and make sure that all requests made by the lync client resolve to an IP address in order to avoid forwarding the a Proxy Server.
