My question is how to restrict user except administrator to create team in MS teams.
can someone help me to resolved this query as soon as possible.
If you want to restrict users to create team, it needs to disable the ability to create groups in Office 365. Since Office 365 group is integrated with many Office 365 services, such as Teams, Outlook, SharePoint, Yammer. If you'd like to disable the creation of teams, all the other services will be also disabled. Currently there's no way to just disable the team creation for Teams users only.
For more details about how to disable this feature, you could refer to this article:
