Unable to "retrieve mailbox" with IMAP4 account

#1966

New mail mate user.

When I try to refresh my IMAP4 account the source is listed as "Unavailable".

I attempted to edit the account and verify the changes by connecting with the "edit subscriptions" dialog box however this returns "Unable to retrieve mailbox\Error ""[OK]"

The logs seem to say that the connection was "successful" and the user was authenticated but not connected. Any idea why/how to resolve this?

I've done the standard things like updating to the latest release and restarting program/computer.

I don't control the server (work account), but need to be able to use this particular email account with MailMate.

    It's actually telling you the problem and how it handles it:

    Warning: Detected Exchange IMAP server response state bug. Trying to work around it by interpreting it as a temporary connection issue.

    This is a workaround which exists because Exchange IMAP servers some times “lose” their connection to some backend. This is a server issue and there's nothing MailMate can do about it other than trying again a bit later (which is why it says “unavailable”). The BAD response is an incorrect response (since it indicates a syntax problem), but MailMate detects it such that you won't see a requester every time it happens. Exchange IMAP servers can be somewhat unreliable.

    You need to contact the IMAP server administrators if the problem persists... Oh, I see that it's an office365.com server. I hope that means it's a question of time before the issue is fixed server-side, because I really cannot do anything from my end.
