Hi there, I keep getting the error message below and unable to log into the Team meeting (both desktop and browser versions). Can you advise me on how to fix this issue for good? I'm a Macbook user, and I have tried both Chome and Safari, and the problem persists. Thank you!

AADSTS90072: User account '******@hikaruvongdesign.com' from identity provider 'live.com' does not exist in tenant 'MSQ Partners' and cannot access the application '5e3ce6c0-2b1f-4285-8d4b-75ee78787346'(Microsoft Teams Web Client) in that tenant. The account needs to be added as an external user in the tenant first. Sign out and sign in again with a different Azure Active Directory user account

    You need to be added as an external user in the 'MSQ Partners' tenant. This process is known as B2B collaboration in Azure Active Directory. The admin of the 'MSQ Partners' tenant needs to send you an invitation to join their organization as a guest user. Once you accept the invitation, you should be able to access the Teams application in the 'MSQ Partners' tenant.

    Thanks,

    Hi @Hikaru ,

    Thanks for reaching out.

    The error code AADSTS90072 is due to the external account that the user signs in with doesn't exist on the tenant that they signed into; so the user can't satisfy the MFA requirements for the tenant. The account must be added as an external user in the tenant first. Sign out and sign in with a different Microsoft Entra user account.

    To resolve the issue, check if the user account exists in Azure AD Tenant. If the user doesn’t exist in the tenant, add them to your Azure AD. If the user is present, check if the invitation is accepted; If not, ask the user to accept the invitation.

    You can also refer this link to see if it can solve the problem for you: - https://windowsreport.com/aadsts90072/

    Hope this will help.

    Thanks,

    Shweta
