Office 2021 Outlook Intermittently Not Connecting To Mail Server

My Classic Outlook will work for weeks or even months and then all of the sudden asks me for the password to my comcast mail account, which has not changed. The only way for me to resolve this is to run an online repair of Office 2021. Google told me to recreate my profile, but when I got to add a new profile it says the profile already exists. I hesitate to remove my account because I don't want to lose all my mail. Any suggestions would be appreciated.

 

Update. I backed up my mail file then removed it and created a new one. It's gonna take some time for the mail files to sync from the server, Fingers crossed.........

 

One last update. Creating that new mail file seems to have resolved my issue. Outlook has been connecting to the Comcast mail server and syncing as designed..........
