Hi Michael. An Outlook EAS profile will not support a POP .PST file. I've been able to convert a POP account to EAS by using these steps.
- In Outlook, save the POP .PST file to the HDD.
- Remove the POP profile from Outlook.
- Set up that profile again as IMAP in Outlook.
- Import the .PST file into the IMAP account.
- Once the IMAP account has synced with the SmarterMail server, remove the IMAP profile, and then re-add it as EAS.
I hope this helps.
