CRM 2022 R2.2 Exchange 365 integration failure to Import Emails after changing password

Hello Sage CRM users,
Has anyone seen this or any ideas what's going on ?. After setting up the Exchange integation for CRM 2022 R2.2 according to the documentation, Import emails has been working. But after changing my password in Windows , I can't re-authenticate. The Preferences/Switch Email Account button seems to allow me to select my email account without any error but when trying to import emails, the error is displayed:  

"AADSTS50173: The provided grant has expired due to it being revoked, a fresh auth token is needed. The user might have changed or reset their password."

I've tried clearing data/cookies in Edge, Edge inPrivate mode, different computers/VMs.. 

I also noticed I can't switch mail accounts either, again the switch email process shows no error , but when importing emails, only the emails from the account I initially connected to are loaded. 

I'm also concerned that the same thing will happen when the OAuth refresh tokens expire after 90 days. 

thanks for any help

Harvey
