Used the pro version to migrate data from OST to PST. It worked like a dream; fast and without a problem. Had to ask Tech Support a question about migration to Office 365 mailbox. The answer came very quickly. Would have liked a solution within the app but guess that's Microsoft limiting what can be done from 3rd party apps. OST2 gets my vote."
