Please prevent Teams from creating team names that match existing groups in Active Directory
Currently it is possible for users to create any team name including using the name of an existing AD group. This allows someone to create a fake/duplicate group name and direct email to it.
Current work-around is to demand all team names are prefixed with a standard code sequence like O365.

How do you DEMAND this? We have settings in O365 Groups that force "O365-" before a name. Can this be done in Teams also?
