Hi team, I have signed out from microsoft word from my old university account. Yet when I try to sign in, the university login box pops up; I can't even go back to sign in with my email. I just bought a subscription using my personal email, but the thing is the word looks like it hasn't been signed out properly since I can see the previous history docs. The sign-in button keeps on loading and only works when i try to hover the cursor trying to close it. And when somehow it gives me a sign in option, an error code comes up. like below-Request Id: 4b2f3a59-c212-484e-8bf6-15d039962e00

'******@outlook.com' from identity provider 'live.com' does not exist in tenant 'Curtin' and cannot access the application 'd3590ed6-52b3-4102-aeff-

aad2292ab01c'(Microsoft Office) 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

Hello,

You want to remove the old university account from macOS

Select Finder > Applications > Utilities > Keychain Access.

Right-click the account that you want to remove.

Select Delete [account name].

=======

Then please use the instruction here: https://support.microsoft.com/office/how-to-remove-office-license-files-on-a-mac-b032c0f6-a431-4dad-83a9-6b727c03b193 Download and run the license removal tool to clear the cached organization credential, this should then allow you to sign in using your personal Microsoft account.

==========

If for any reason it still doesn't work, I need to know your macOS version, because it can be a separate issue that's also going on at the same time.
