I have synchronized msRTCSip with Online.
Following are the Outputs:
HostingProvider : sipfed.online.lync.com
InterpretedUserType : AADConnectEnabledOnlineTeamsOnlyUser

 

Trace:

when i synchronized ,

InterpretedUserType changed to AADConnectEnabledOnlineTeamsOnlyUserNeedsProvisioningToAD

then after some time it got updated to AADConnectEnabledOnlineTeamsOnlyUser

 

But still external chat is not activate in teams.
