Outlook for Mac Repairing Main Profile

I'm running Outlook on my MacBook Pro running MacOS BigSur 11.7.10. Have received a dialog box stating "Repairing Main Profile" and "Copying Records to a new Profile". This has been going on for about 2 hours so far. I have no access to any Outlook commands . How long will it take to do this repair or is it a never ending loop. Suggestions, please
