Why does Lync client Configuration Information say UCS Connection State Exchange Connection Down ?

17/12/2011 5 Comments

 

I’ve been asked this one a couple of times from customers now so thought it would be worth clarifying. First of all, how do you see Lync client configuration information

A standard right click on the Lync tray icon will give you this menu

but, if you hold ctrl and right click you will get an additional configuration information option

Click it and you will get all kinds of useful configuration information. In this case, Lync is working perfectly, including conversation history and visual voicemail. We can see MAPI and EWS status are ok, so why does it say UCS Connection State Exchange connection down?

The Answer:

UCS stands for Unified Contact Store which according to that link allowed you to store your contact list on exchange, but the feature was dropped from Lync 2010 RTM. So it won’t show as connected and you don’t need to worry about it.

Hope that helps.

    Apart from that single technet article, I cannot find any other reference to the statement about dropping this feature (not even an official statement from MS), so either that guy in the technet forum is a more-than-well-informed insider, or he just shares his own “feelings” without any way to confirm what he’s saying is true or false.

      I can’t find any official statement to reference, but since it was never an RTM feature that seems unlikely. However I trust Tom Pacyk and have had it verified from other people offline.

        Contacts Enhancements –> If your organization has deployed Microsoft Exchange Server 2010, a single unified contact store for contacts across Lync, the Microsoft Outlook messaging and collaboration client, and other endpoints eliminates the need to maintain multiple contact lists, and provides a consistent experience across programs.

        Actually that may just be marketing bullsh*t (only the writer of this article can translate what this fancy paragraph should really mean to customers)

  2. Randy Wintle says:

    I can confirm there was an additional feature, where there would be a true contact store that was shared between exchange and Lync that was cut from the product.

    This is often confused with Lync’s ability to create contacts in exchange, and exchange contacts to show in lync searches.

    Tom’s article is correct. Take it from someone who was working with the product in the early betas and heavily involved throughout the entire process…
