Hi everyone,

 

we have a Tenant with multiple added domains.

- domain.com (default)

- domain.net

- ...onmicrosoft.com

 

Users are synched from On-Prem to AAD.

They show up in the AAD directory with proxy adresses like that;

 

User Type A:

  smtp:user@...onmicrosoft.com

  SMTP:user@domain.com

  ....

 

User Type B:

  smtp:user@...onmicrosoft.com

  SMTP:user@domain.net

  ....

 

Both types of users have assigned E3 licenses.

 

So far... everything ok and as expected...

 

But now...

User Type B cannot search external users in MS Teams.

After I've checked a few things, I could find a difference in the users list in the MS Teams admin panel.

User Type A: Directory status "Online"

User Type B: Directory status "Unknown"

(there is also a User Type C: Directory status "Unlicensed")

 

For me it seems like a missing (license?)-connection from the tenant-user to the teams-user?

 

Any ideas or recommendations to fix it?

 

Thanks,

Patrick

@trepach if I had to guess, and just spit balling here, I suspect the whole domain probably has that issue. I would suspect they are in Island mode and missing DNS entries for Skype for Business. You should try switching the user to teams only mode, or the domain to teams only coexistence mode, or just adding the public Skype4Business DNS entries for the domain.
