Free methods to convert OST to PST

If you're looking for free methods to convert OST to PST, here are some reliable approaches:

1. Using Microsoft’s Native Methods (Free)

a. Recreate Outlook Profile & Export to PST

Since OST files are offline copies of Exchange mailbox data, you can reconnect to the Exchange server and export data to PST:

1. Open Control Panel > Mail > Show Profiles.

2. Add a new profile and set up your Exchange account.

3. Once synchronized, open Outlook, go to File > Open & Export > Import/Export.

4. Choose Export to a file > Outlook Data File (.pst).

5. Select the folders and save as PST.

Limitation: Requires access to the original Exchange server.

b. Use Outlook’s Archive Feature

If you can open the OST in Outlook:

1. Go to File > Info > Cleanup Tools > Archive.

2. Select folders and choose PST as the destination.

2. Using Free Conversion Tools (Third-Party)

Which Method Should You Choose?
