I have been having the same issue for months. Just in case it is
relevant, the issue does not happen to my work Office 365 account, only
my personal one.

I'm facing this issue on 6065 and it persisted when I upgraded to
6292, on a M1 MacBook Pro with Tahoe 26.5.2. For the past few months,
my Outlook account pops up a prompt to approve MailMate's access every
day. I'm using OAuth2 with outlook.office365.com as both IMAP and SMTP
server, and almost all the time, the issue doesn't resolve by
approving access on the web page, it keeps popping up the page again &
again after each approval till it stops. After relaunching MailMate,
approval works again and I only have to approve it once. But the cycle
repeats every day. I captured the logs for one full cycle and in the
non-working state (before the relaunch), there are 3 command streams
in the log, I've uploaded all 3 with some redactions below. It starts
with the error "D3 NO User is authenticated but not connected.”.
Command attempted: “D3 AUTHENTICATE XOAUTH2
••••••••••" and ends in the perfectly good refresh
tokens (and the access token and expiry date) being deleted from the
keychain. Has anyone faced this ?
