Sorry I haven't been able to provide enough info on this.  It comes
and goes, but I suspect it's partly based on how many filed and
deleted messages you have.  If I do more than... oh... say 8 to 10
messages which are filed and deleted, then try to expunge them from
the IMAP server, it then fails.  Again, I suspect it's because MS
Exchange has a poor IMAP implementation.

Could it be that the server says "whoa, too many bad commands, I'm
kicking you out!" so it might be useful to do the commands in smaller
batches, then flush changes?  

Or maybe, because MS Exchange just sucks, we don't store any flags
beyond the ones defined in the IMAP standard?  Or maybe we need to
pre-define the 'filed' flag as a PERMANENTFLAGS somehow?  Yes, I'm
quickly looking over the IMAP specs as shown in:

  https://tools.ietf.org/html/rfc3501#section-6

Sometimes it works, in other words, I can save the buffer, expunge
deleted messages, etc.  Othertimes the IMAP connection gets closed and
I don't get to make any changes at all to my inbox. I then have to
login with Outlook, find and nuke some/all of the messages giving
problems, and then VM works again.

Uday> Yes, there is.  Please see the manual section "Message Attributes".
