Quick method to transfer emails from OST to PST in Outlook2025?

Yes, you can migrate an Outlook OST file to PST format, but the method depends on your specific situation.

1. If your Outlook profile is active and connected to the email account, you can easily export the data to PST:
  • Open Outlook.
  • Go to File > Open & Export > Import/Export.
  • Choose Export to a file, then select Outlook Data File (.pst).
  • Select the top-level folder (usually your email address).
  • Click Next, then Browse to choose a location to save the PST file.
  • Click Finish to export.
Alternatively, if you're moving to another system and the account is still valid, simply logging into Outlook on the new system will automatically recreate a fresh OST file.
2.In cases where the OST file is orphaned and cannot be opened via Outlook, built-in options won’t work. You’ll need a third-party OST to PST converter tool to extract and migrate the data.

While many such tools are available online, not all are reliable. A commonly recommended option is GoldyTools OST to PST Converter, which often appears at the top of search results and is endorsed by professionals on platforms like Spiceworks, Experts Exchange, and Microsoft TechNet.

You can also try free trials of other reputable tools to see which works best for your needs.

Let me know if you'd like a shorter version or formatted for a particular use (e.g., blog, email, helpdesk guide).
