Teams External User

Copper Contributor



After we have enabled the Sharing Teams and adding another domain, some user who still on SFB couldn't reach the externe user, 

So i upgrade them with the powershell command : Grant-CsTeamsUpgradePolicy -PolicyName UpgradeToTeams -Identity


But now i have another issue , the external can be found but we can't chat them.


"due to changes in organization policies, some chat and calling features are no longer available"
