Before we fix the issue, let’s take a look at underlying causes for it.

What causes the Aadsts90072 error?

The following are potential causes for the AADSTS90072 error:

• Account doesn’t exist in the tenant – if the external account that the user is trying to sign in with doesn’t exist on the tenant that they signed into, it can prompt the error. Also, it is because the user can’t satisfy the MFA (Multi-factor authentication) requirements for the tenant, making it unauthorized.
• There is a mismatch in the ImmutableID attribute – The error can also occur if there is a mismatch in the ImmutableID (sourceAnchor) attribute between Active Directory and Azure AD regardless of the users being synced.

These factors can vary on different computers depending on the condition. However, we’ll take you through detailed steps for fixing the issue.

How can I fix the Aadsts90072 error?

Before proceeding with any advanced troubleshooting steps, try the following preliminary checks:

• Restart your PC – Restarting the computer will fix temporary issues affecting its performance and refresh its activities.
• Fix network issues – Power cycling your router/modem or fixing network congestion on your computer can help you connect faster to the internet.
• Use the Firefox browser and clear cookies for cookies – Clearing cookies for login.microsoft.com and teams.microsoft.com on Firefox should prevent the error from popping up again.
