Cant add guest user in Microsoft Teams


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.
