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)

3. Manual Conversion via Thunderbird (Workaround)

If you can’t access Exchange:

  1. Install Thunderbird and ImportExportTools NG add-on.

  2. Import OST via mbox format (indirect method).

  3. Export emails to PST (limited success rate).

4. Using Kernel for OST to PST (Free Scan)

Which Method Should You Choose?

  • If you have Exchange access, use Outlook’s export feature.

  • If OST is orphaned, try a free tool (with limitations).
