Following a recent migration and version upgrade (12.x to 13.4.5598), several users are reporting random, relatively infrequent, IMAP UID errors in Outlook. A typical error shows something like this:
MsgSeqNum 3532, New UID 355. Prev UID: 3550, Next UID: 3552.
with an error code of 0x800CCCDC.
Anyone have any ideas what might be going on?
