The Problem with the Ghost or Phantom presence continues, and it might cause more and more problems! Spoiler alter: Microsoft is working on it.
First a wrap-up of the issue itself:
- The Microsoft Teams Clients sets my Skype for Business presence to available (green) as soon as I start it
- When I manually set myself to busy or do not disturb (Both should indicate red) it stays with available (green) as Skype for Business presence
- If I place a phone call or join a meeting in Microsoft Teams (Yep, I use Microsoft Teams more and more) the Skype for Business presence is still available (green)
Chats and calls from Skype for Business arrive on my (iOS based) Smartphone Client, because I don’t start the Skype for Business Client all the time (anymore).
