    Hello,

    I need to test Lync SDK (2013) app with Skype UI suppression.

    I tried all possible registry paths that can be googled

    on Win 8.1 Pro 64 bit with SfB 2015 client and Skype UI is not suppressed after its restart.

    What are the other requirements for suppression? If installed MS Office 2013 and SfB itself are not activated/registered, can it be the reason? Can local or global domain group policy affect UI suppression?

    Windows is activated, BTW.

    Thanks

    Now Office (with Skype) are activated. UISuppression still fails.

    I guess correct registry path is

    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\15.0\Lync

    With UISuppressionMode DWORD key = 1 (BTW, I can see path and key name in my Lync.exe)

    LyncClient.GetClient() can't start host process (gives exception "Hos Process is not running").

    When SfB is launched manually, it has normal UI and InSuppressedMode = false and State = SignedIn

    SfB About window tells:

    Microsoft Lync 2013 (15.0.4809.1000) MSO (15.0.4823.1000) 64 bit

    Skype for Business 2015. MS Office  Professional Plus 2013

    Hi there,

    I've answered this question in my blog post here: http://blog.thoughtstuff.co.uk/2016/07/skypedevq-ui-suppression-in-skype-for-business-client/

    But, the short answer:  the Skype for Business client uses the 16.0 keys to trigger UI Suppression, but the client SDK uses the 15.0 keys. So, keep both happy: add the UISuppressionMode value to both the 15.0 and the 16.0 keys!

    Tested with some trivial sample UI Suppression code: no errors, can get client State.

    Hope this helps,

    -tom
