Hi. A long story made short but one IMAP server that I send to for a group email refuses to forward emails that originate from a specific POP server so I have decided to migrate to IMAP. However, I note I cannot just change the POP to IMAP in Outlook 2013 as POP is greyed. So I created another account using IMAP and the same email address which works fine. My problem is that how do I merge, copy, add my previous .pst file? I only see one file but there is another .ost file which I guess could be IMAP.
Cheers...
