IMAP problem with office365
Reported by Tom Dietel | September 27th, 2017 @ 09:27 AM
Hello,
I have problems with Mailmate connecting to my university's office365 mail server. Every few minutes, a window pops up complaining about an "unexpected end tag", and I have to click "retry".
The log file from the activity viewer is attached.
Please help,
- Tom.

Looking at the log file, it seems as if Mailmate sends a C2 LOGIN before the server sends the response to C1 AUTHENTICATE.

Yes, this appears to be a MailMate bug. I think maybe MailMate times out before receiving the response and due to a workaround for various server bugs (including for Outlook) it quickly retries with a different authentication method. It should, instead, increase the timeout value. I'll look into this.
(You might not see the issue when the server is less busy.)

Hold down ⌥ when clicking “Check Now” in the Software Update preferences pane to fetch a test release (r5421). Then send me new logs if the issue persists.
Thanks in advance.

It seems the fix worked, and I guess we can close the ticket. I have not had any messages in the last two days.
Thanks for the quick response,

Ok, let me know if it returns.
