Yes, you can export OST files to PST format along with all associated data. There are two primary methods to convert an .ost file to a .pst file: manual conversion and using a professional third-party tool.

How to Convert OST to PST Manually​

Follow these steps to perform the conversion using Microsoft Outlook:

1. Open MS Outlook with access to both your Exchange account and the offline mailbox.
2. Go to File > Import > Import Messages and import the OST file.
3. Next, go to File > Export > Export Messages.
4. In the new window, select Microsoft Exchange and click Next.
5. A pop-up will appear saying:
   "This will export messages from the offline mailbox to Microsoft Outlook or Microsoft Exchange."
   Click OK to confirm.
6. Choose to export either selected folders or all folders.
7. Click OK to start the export process.
8. Once the process completes, a confirmation dialog box will appear. Click Done.

Note: This manual method can be quite lengthy and requires a good level of technical expertise. It also depends on having access to the original Outlook profile and Exchange Server, which isn’t always possible—especially with orphaned or corrupted OST files.

You can transfer OST to PST file both by using manual method or by using a third party tool like Stellar Converter for OST. Let me walk you through both the processes.

For the manual method you have to simply use Outlook itself to convert your OST file to PST. Follow these steps to convert OST file to PST manually:

Launch Microsoft Outlook and ensure it’s connected to the Exchange server linked to your OST file.

• Go to File > Open & Export > Import/Export.
• In the Import and Export Wizard, select Export to a file and click Next.
• Select PST Format.
• Select the mailbox or specific folders you want to export from the OST data and click Next.
• Specify a location and name for the new PST file, then click Finish. You can optionally set a password for the PST file.
• Open the saved PST file in Outlook to confirm that all your data has been transferred successfully.

However, as stated earlier this process is only applicable when your OST file is connected to the Exchange Server. But if your OST file is inaccessible and is not connected to the Exchange server, this is when a third party tool like Stellar Converter for OST is required.

One of the main feature of that tool is to convert inaccessible and orphaned OST to convert to PST with 100% precision. You just simply need download the software from the official website and install it. This tool also helps you to convert multiple OST files into PST files in one go with its batch file conversion feature. It also helps you to auto locate your configured OST file to convert to PST file and also helps in converting encrypted OST file to PST file which is impossible in manual method. For more info, download the software from official website.
