Only admin should be creating teams
Give businesses option to only have Office 365 admin to create Teams. Currently any user can create a team any way they want and my employers want only admin to create teams so that there is a consistent naming structure to team names. Also they don't want users creating teams with private chatting to external users that no one knows about using resources that the company has paid for.
just create a security group, add all your O365 Admins and just allow them to create Teams/Groups (https://docs.microsoft.com/en-us/microsoftteams/assign-roles-permissions)
