NOOP is a "no operation", so it does nothing itself. But as part of all
commands IMAP server checks if there have been any changes to mailbox
and notifies about them (new messages, flag changes, expunges). I know
Outlook used to become confused about those flag change events when they
were sent as a reply to FETCH command, but all server do this checking
for NOOP command, so I've no idea what Outlook's problem with it could
be.
