Experiencing authentication issues

Question

I basically can't do anything on the azure portal. The message I get is as follows:

There are other versions, sometimes the application is ADIbizaUX instead of azure portal.
I have tried this in multiple browsers. Dev tools show that I am getting a bunch of 403 responses:

All the other similar questions suggest that there is an issue with my account permissions but none of them explain how to fix it or even where to look for troubleshooting.

Answer 1

The message generally means that the external account that the user signs in with doesn't exist on the tenant that they signed into. This error also might occur if the users are synced, but there is a mismatch in the ImmutableID (sourceAnchor) attribute between Active Directory and Azure AD. The account must be added as an external user in the tenant first. You may need to sign out and sign in with a different Azure AD user account, and then add the other account.

This might be due to this being a personal account. In that case you can try this:

Sign-out of your personal account from https://account.microsoft.com/ or another Microsoft web page.
Sign-in again to the service and verify the "Work or school account" option is selected. There is a link to allow you to rename your personal account so it no longer causes this conflict. https://go.microsoft.com/fwlink/p/?LinkID=733247

Answer 2

I am also getting the same error, please help!

Answer 3

I am also running into this problem with a new account, and old ones that didn't have Azure setup before. With an account that had tenants, I'm having no issues, but I can't really use other accounts to create new tenants. Any updates on this?
