Step-by-Step OST to PST Export Procedure for 2025

[RayAllen]

To export OST mailboxes to PST manually, follow the steps below. Make sure you're logged in to Outlook using the Exchange account that was originally used to create the OST file.

Step-by-Step Guide:​

1. Open Outlook and go to:
   File > Open & Export > Import/Export
2. In the Import and Export Wizard, select:
   Export to a file, then click Next
3. Choose:
   Outlook Data File (.pst), and click Next
4. Select the mailbox folder(s) you wish to export (e.g., Inbox, Sent Items), then click Next
5. Click Browse to choose the destination where you want to save the PST file
6. Choose your preferred option for handling duplicate items, then click Finish
7. (Optional) You may set a password for the PST file for added security, or simply skip this step to proceed without one

This method is ideal for small to moderate mailbox sizes. For larger or damaged OST files—or if you no longer have access to the original Exchange account—consider using a professional solution like GoldyTools OST to PST Converter for a safer and more efficient conversion.
