Wondering if anyone has run into this in the Horizon world since this is the only place I've seen this. I am having a trouble with user presence from S4B populating in Outlook if Outlook is opened before Skype. But this is only in Horizon IC's that I see this. On my physical machines, if I open Skype after Outlook has been opened, presence populates within a few seconds of status being completed in the S4B client.
In instant clones I have to restart Outlook to get presence to populate. Might be better off posting to a MSFT forum, but posting here in case anyone else has seen this.
