  3. Signing out of any accounts tied to their mailbox Gmail etc..
  4. Tried running Outlook in safe mode
  5. Uninstalled Reinstalled Office (latest version)
  6. Downloaded and ran the troubleshooting tool for o365

    Found the user's personal email was trying to log into their work account. Going to Settings -> Account ->Email & Accounts and removing their personal account and adding their work account corrected the issue.
