The domain you are trying to sign in to doesn't have any users that have a Microsoft Teams or Skype for Business Online license assigned to them. Learn more
Here are things you can try to fix this:
Assign a license - Go to Microsoft 365 admin center > Users > Active users and make sure that there is at least one user in the domain that has a Microsoft Teams or Skype for Business Online license assigned. If you have recently assigned a license to a user in this domain, it may take up to 24 hours to take effect.
Buy a license - If you're just setting up Teams, go to Microsoft 365 admin center > Billing > Licenses, buy some Microsoft Teams licenses, and assign them to your users. It may also take up to 24 hours to take effect once you assign them.
Contact us - If you have assigned a Microsoft Teams license to at least a single user, but you are continuing to see this message, contact Microsoft customer support.
