How to Convert OST to PST in Outlook 2007 Freeware

 If you’re using Outlook 2007, you might run into issues with offline Outlook data files called OST files. These files store your emails, calendar, contacts, and other data when you’re using Exchange or IMAP email accounts. But what if you want to move that data to another computer, keep a backup, or open the data in Outlook again?

That’s where OST to PST conversion becomes important.

In this blog, we’ll explain in simple, easy-to-understand words how to convert an OST file into a PST file in Outlook 2007, using free methods and OST to PST Converter Tools.

📌 What Are OST and PST Files?

Let’s begin with the basics.

  • OST (Offline Storage Table)—This file lets you access your emails even when you're offline. It syncs with your mail server when you're connected again. But you can’t open OST files directly in Outlook unless they’re connected to the original profile.

  • PST (Personal Storage Table)—This file stores emails, contacts, calendar, and other Outlook items locally on your computer. PST files are easy to move, back up, and import into Outlook.

When you want to move your data from one computer to another, or when Outlook can’t open your OST file due to corruption or profile issues, you’ll need to convert OST file into a PST file.

❓ Why Convert OST to PST in Outlook 2007?

You might need to convert an OST to PST if:

  • Your Exchange account is no longer available.

  • Your Outlook profile is deleted or corrupt.

  • You’re switching to a new computer.

  • You want to back up your emails.

  • You want to open an old OST file in Outlook 2007.

And because Outlook 2007 doesn’t have a direct option to open an orphaned OST file, the best solution is to convert it into PST.

🔄 Free Method to Convert OST to PST in Outlook 2007 (Manual Way)

If your Outlook profile and OST file are still working, you can convert the file to PST manually using the built-in export option.

Step-by-Step Guide:

  1. Open Outlook 2007 with the profile connected to the OST.

  2. Click on File > Import and Export.

  3. Choose Export to a File, then click Next.

  4. Select Personal Folder File (.pst) and click Next.

  5. Choose the folder(s) you want to export. To include everything, select the top-level mailbox and check "Include subfolders."

  6. Click Next, then browse to select where to save the PST file.

  7. Click Finish.

Your OST data will be saved into a PST file that can be easily moved or opened on any Outlook setup.

✅ Note: This method only works if Outlook is working and connected to the original profile.

🚫 Limitations of Manual Method

Manual OST to PST conversion has a few drawbacks:

  • It won’t work if your Outlook profile is broken.
