Logging into Teams for the first time and get error message

Amber Trevaskis-Bloomer 0 Reputation points

I just downloaded Teams and need to get it set up to use with a client. But when I try to access, I get the following error message:
"Selected user account does not exist in tenant 'Microsoft Services' and cannot access the application '1fec8e78-bce4-4aaf-ab1b-5451cc387264' in that tenant. The account needs to be added as an external user in the tenant first. Please use a different account."

I'm not technical and don't know how to fix this. Any suggestions?

    Hi @Amber Trevaskis-Bloomer

    Do you have the same issue when login Teams web client?

    To resolve this issue, you need to add the user account as an external user in the tenant. This can be done by following these steps:

    1. Log in to the Azure portal using an account that has the necessary permissions to add external users.
    2. Navigate to the Azure Active Directory blade.
    3. Click on the 'Users' blade.
    4. Click on the 'New guest user' button.
    5. Fill in the required details for the new user and invite them to the tenant.
    6. Once the user has accepted the invitation and their account has been created in the tenant, they should be able to access the application using their account.
