We've been using your API for downloading message via IMAP for some time now. We just ran across a case where we had a 30 minute window when we got the following error returned when trying to download the header list. I'm using 2013R2. Any thoughts on what might cause this error message?

Rebex.Net.ImapException: Unexpected IMAP EXPUNGE response.
