Converting your Outlook OST file to PST format depends on whether your Outlook profile is still connected to the Exchange Server.

1. If Outlook is Connected to Exchange

When your Outlook account is active and synchronized, you can use the built-in Import/Export feature to export mailbox data:

Go to File → Open & Export → Import/Export → Export to a File → Outlook Data File (.pst)

This method works only if the OST file is accessible within Outlook.
2. If the OST File is Orphaned or Inaccessible

If your OST file is orphaned, corrupted, or from a deactivated mailbox, Outlook won’t open it directly. In such cases, a specialized recovery tool offers a faster and more reliable solution.
