Microsoft Outlook offers a built-in option to export OST files to PST format. This is a free method and can be useful for users with access to their Outlook profile. Here's how to do it:

🔹 Steps to Export OST to PST Using Outlook:

Launch Microsoft Outlook.

Click on the File tab in the top menu.

Choose Open & Export and then select Import/Export.

In the wizard, select Export to a file and click Next.

Choose Outlook Data File (.pst) and click Next.

Select the mailbox or folder you wish to export, then click Next.

Browse and select a location to save the PST file.

Click Finish to complete the export process.

⚠️ Limitation:

This method does not work with orphaned, corrupted, or inaccessible OST files (i.e., OST files not connected to an active Outlook profile). In such cases, Outlook cannot access or export the data.

If you're dealing with an orphaned OST file or facing errors with the manual method, you’ll need a reliable third-party tool. One such trusted solution is the GoldyTools OST to PST Converter.
