Hi @Alex J ，
Since your email address has been disabled, you can't connect to the server, so you will encounter continuous password prompts. It is recommended that you try to switch Outlook to offline mode to see if there is a password verification pop-up box.
To make Outlook work offline: on the Send/Receive tab, choose Work Offline.
Besides, you can export or back up email, contacts, and calendar to an Outlook .pst file.
