Coexistence mode Teams only

[AusSupport180]

Hi,

 Migrated to Teams Only and removed all the on-premises Lync servers.

Do we still need the script to set a user account for Microsoft Teams Only?

Grant-CsTeamsUpgradePolicy -Identity $Arg1 -PolicyName 'UpgradeToTeams'  

When the users are terminating, do we required to remove the number assigned? Or when we remove the O365 user License group will take care of that?

Hi, you should be good by simply running the Global tenant setting.

Don't think you have to bother about the latter really.
