re: POP/IMAP converted to Exchange

So you’ve got hosted email with that subscription, meaning you don’t need anything related to Exchange. It would seem that you just need to add your new email to Outlook and can copy over all emails. Or you can go into current email and export all mail/contacts/calendar to a file (usually in pst) then make “new profile” in outlook and attach/import the mail/contacts/calendar. Once all copied over you can detach/disconnect the pst and delete the old email profile (or leave it for time period to be safe)
