HI all for your information this post describe a update of our attempt to delivered a stable Lync 2013 Citrix Vdi environment to our users on Xendesktop 7.5
A complete history could be found here: https://unifiedit.wordpress.com/category/2-lync-2013/lync-2013-vdi/
Since a while, we try to stabilize the Citrix VDI environment with Lync 2013 on Xendesktop 7.5. The last issue before delivering this solution to our User pilot was to fix the Ctrl Alt Tab issue (for more information see this article). https://unifiedit.wordpress.com/2014/03/07/lync-2013-vdi-citrix-alt-tab-issue-is-back/. For this a Microsoft Case has been opened and the last action was to update the Lync 2013 client with a May 2014 patch (http://support.microsoft.com/kb/2880980). As the following picture display

After applying the update we can observe that the Ctrl Tab Issue is no more present
but when the user close the session the Ucvdi.dll of HDx Engine crash.
