FWIW, I've been having the same experience with Exchange 2010 and Gcc;
it used to work well with Oct-Nov gnus git versions but started to show
issues occasionally in Dec gnus git versions; lately it has become
relatively frequent for me, at least a few times per day.

Exchange IMAP is understandingly not among primary Gnus test platforms.
Thinking also of gnus agent nnimap features that have low TODO priority
such as moving email between folders when unplugged, perhaps it's time
to plug dovecot and offlineimap between gnus and Exchange so as not to
connect to Exchange directly?  This setup could be both (i) more robust
(since people using other MUAs like mutt are using offlineimap for
Exchange too, so any intricacies of Exchange IMAP may be better handled
there); and (ii) more advantageous offline-feature-wise (e.g. the
above-mentioned moving/triage of email between IMAP folders when
unplugged).  Though there were also some issues WRT offlineimap and
marks, for example, so dunno.

Does anyone with `corporate Exchange' have first-class experience with
such a gnus-dovecot-offlineimap-exchange setup for a reasonably long
period of time?  Personally I tested such a setup only briefly, and only
with old nnimap.  (I preferred to keep the gnus agent way of doing
things at the time.)
