Using New Outlook on Windows for personal email, calendar, and contact management
Hi Susan. I am not with microsoft. I can only share what worked for me. You need to remove the account that is not working from the outlook client. When it asks if you want to remove from just this device or all devices, you need to select all devices. Once you have completed removing the account, you need to re-add back to the outlook client. Once done it should work and will just take a while to sync back up.
