Cant add guest user in Microsoft Teams

Frequent Contributor

Hi All, 


We are trying to add an external person collaboration in Teams and added the person in External Access domain as follows: 


  • 01 Extrnal Access.jpg
  • even after 48 hours, we are NOT able to add the person in Teams Admin Center 

    02 Cant Add User.jpg

  • The AAD External Access are enabled 
    03 AAD External Use Settings.jpg

What could be potential reason that we could not add the person. 
Please advice.
