outlook is somehow automatically marking all my emails as read via imap for my host's emails. i've tested it. i send myself a bunch of emails and it takes about a second and a half for outlook to automatically mark them all as read at once, no matter what the subject is or what the email's contents are or where the emails are coming from. this only happens in outlook and nowhere else i check my host's email via imap. this is a fresh outlook install with no rules set or anything.

I would start here
