Every sync takes 10 minutes due to many messages missing from remote

Thanks, Nicolas. I've filtered that folder now, as well as other Outlook
folders not of interest to me, and that's helped.

I'm curious how I can retrieve calendar information, though, so that I can
add meeting invites to my remind calendar. The Office 365 server sends an
HTML email that simply contains a link. If I follow the link, it just takes
me to my WebMail inbox. None of the mail headers seem helpful. The
Lightning add-on for Mozilla Thunderbird is able to retrieve meeting
invitations, so there must be a way. I guess the add-on contacts the
Exchange Web Service (EWS) periodically for invitations and the email must
be useless and irrelevant.

If OfflineIMAP only syncs mail, then I'll need to look for something that
can sync my Office 365 calendar with remind, or make my own utility. I
don't want to keep missing meetings. :(
