That's USR1 on my linux machine.  It gets sent by idled.  If
idled still thinks you're idling, but your imapd doesn't, 
then it's not trapping USR1 any more.

That's potentially a bug.

Possibly.  It would be interesting to see the telemetry logs.  I suspect
that Outlook is doing something funky with idle, but assuming that it's
changed recently, we might also be doing something odd with idle in
Cyrus that's causing it to break.

If you are able to get telemetry logs (create a directory
$confdir/log/$user/ - i.e. /var/imap/log/brong in my case,
and make sure it's owned by your cyrus user) that would be
a great help.  Obviously remove any identifying data you're
worried about being public, and just send it to me if you
want.  I'd like to see what it's doing!

Thanks,
