    Thank you. This helped a lot.

     

    I tried

    Grant-CsTeamsUpgradePolicy -PolicyName UpgradeToTeams -Global

     and got

    This organization cannot be upgraded to TeamsOnly at the tenant level because there is an on-premise deployment of Skype for  Business detected in 1 or more of it sip domains, xxxx.yyy. Users can be individually upgraded to TeamsOnly using either Move-CsUser (if the user has an on-premises Skype for Business account) or Grant-CsTeamsUpgradePolicy (if the user is homed in Skype for Business online).

     

    Then I tried

    $userlist = Get-CSOnlineUser
foreach($User in $userlist)
{
 Grant-CsTeamsUpgradePolicy -PolicyName UpgradeToTeams -Identity $User.SipAddress
}

     

    And this worked for me. Case closed. 😉
