I have Outlook 2013 with a MS Exchange account and my @btconnect.com account set up as POP with a separate .pst folder to which it delivered incoming & sent mail. I used to have Outlook 2007 on old PC with the exact same set up.
Since I've upgraded to the new PC with Outlook 2013 the @btconnect.com account has started delivering incoming mail (only not sent items) to BOTH the Exchange mailbox AND the separate .pst file.
This is unbelivably bugging and totally unnecessary!! How do I prevent this from doing this?
