Additional features, settings, or issues not covered by specific Microsoft Teams categories
Hi @IBN
You could try to follow these steps to restrict users to create Teams using their Office365 accounts:
- In the admin center, go to the Groups > Groups page.
- Click on Add a Group.
- Choose Security as the group type. Remember the name of the group!, I will use “AllowedToCreateOffice365Group” in my example.
- Finish setting up the security group, adding people or other security groups who you want to be able to create groups in your tenant
