Brass Contributor

Hello everyone,


Recently I have been noticing that I can't see a presence for federated users (Teams external users).

from the Teams, I can see their presence.

but outlook show them -"presence unknown"



For some of my customers, I can see their presence on the outlook.

my Coexistence mode - Teams Only ( also my federated users).

also, my Teams register as a chat app.

and I configure Teams as the chat app.


I found this information in Microsoft -

Hello ChristianJBergstrom
So you said their Resolution not related to this Symptom -
"Outlook currently shows Status unknown for federated (external) Teams contacts."

just to :
The presence indicator is not visible.

The displayed presence is incorrect.

The presence status is Status unknown.
Is there an update on this issue - "Outlook is currently displaying an unknown status for unified (external) group contacts."

thanks for your help.

I dont work for Microsoft. Open up a support ticket as the article also mentions for more info.
