This is a different error message from Microsoft after an apparent corruption in the logged in user’s profile.

Prior to this received the TPM Error code 80090016 – See this blog post for correcting this one: https://jvhconsulting.com/2022/10/20/error-code-80090016-tpm-has-malfunctioned/

Searching the web for answers found a few links to do the following:

1. https://www.thewindowsclub.com/microsoft-sign-in-error-1200-something-went-wrong – lists a number of things to do
   • clear browser cache – doesn’t do anything but lose all the browsing history and important things
   • Delete Credentials folder – from users profile\appdata\local\microsoft\Credentials – While I didn’t try this, don’t think it would help.
   • Perform a Clean boot – use msconfig.exe to set next startup to be clean boot – nothing in startup items.
   • Open Credential Manager from Control Panel and clear out the web credentials for office – didn’t work.
   • Delete the Identity Key in registry here: HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Common\Identity
     • this didn’t work either.
2. The Solution from a few searched sites, is to go to Settings – Accounts – Access Work or School selection – on the right side, click on each of the accounts and choose Disconnect. I believe this is the answer to this error code. Thereafter you can open Outlook, sign in again to each of the email accounts and it should work fine from there.

Cheers!
