Using Office 2013 (64bit)
I have several pop3 accounts that are all using outlook.pst file.
I just created an IMAP account and that is using a OST file.
Is there a way for the IMAP account to use the same outlook.pst file
No, sorry, you can't use the pst file as the delivery location. You can use rules to move mail but that deletes mail from the server. You could also use POP3 with that account, if supported.
