The error was on selecting a folder:

That error could indicate a broken connection that will work when we
restart offlineimap, but it could also indicate that the IMAP server has
fallen over and will give that reply for every single communication
attempt. That's why I am a bit cautious in simply dropping a connection
on such an error and retrying. I don't want to bring down entire
exchange servers by an infinite loop trying to select a folder :-).
