How to convert OST to PST file Manually?

Here are two manual solutions to migrate OST to PST files. You can select anyone which suits you.

• 1st Method: Use Auto Archive to Convert OST to PST file
• 2nd Method: Use Import/Export Feature in Outlook
• 3rd Method: Use Professional Regain OST Converter tool

Method 1: Use Auto Archive feature to Convert OST to PST file

The first method to convert OST to PST is to enable archiving in Outlook once your Exchange account is configured. When you enable archiving in Outlook, it automatically moves archived email into a new PST file format and helps maintain an optimal mailbox size.

Here, you need to follow the steps to configure Outlook archiving.

• Step 1: Open Outlook and hit the “File” option.
• Step 2: Click on the “Advanced” option, and a new wizard will open on the screen; select “Auto Archive Settings” in the “Auto Archive.”
• Step 3: In a new Window, select the number of days to run auto-archiving and hit “OK.”
• Step 4: Save your mailbox items from the OST file to PST by enabling the archiving option.

Method 2: Use Import/Export feature to Convert OST to PST

All MS Outlook versions are embedded with built-in import and export, allowing users to transfer OST data to a PST file quickly. This method only works when your OST file is connected to the Exchange Server while exporting. Also, it is useful when making a local and portable backup of Exchange Mailbox data.

Follow these steps to use Import/Export feature in Outlook:

• Step 1: Launch the MS Outlook application. Click on the ‘File’ tab >> “Open & Export” >> “Import/Export.”
• Step 2: Choose the “Export to a file” option and click the “Next” button.
• Step 3: Select the “Outlook Data File (.pst)” option, then click on “Next.”
• Step 4: Select the folder you want to convert into PST files and tap Next.
• Step 5: Click the “Browse” section to choose the destination folder where you want to save the PST file in your system. Now, hit the Finish button.
• Step 6: Add a password to your converted PST file or continue without it. The conversion process will start and end as per the data size.

Both methods will work when your data is low. To continue this method, you need Outlook permanently connected to the Exchange Server; therefore, it does not convert orphan, corrupted OST files. The possibility of data loss during conversion is also common in these manual methods.

However, many users claim they lost some of their data in that PST file. But if you don’t want to face any issues during OST to PST Conversion, I strongly recommend using the third-party OST Converter tool developed by Regain Software.
