How to convert Outlook OST files to PST file format. Use Free OST2 Software.

img-quote - John J, USA Rating: 4.9 - 406 reviews

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."
