Convert Your OST File to PST (An Alternative to Save Data)

The data across an OST file is quite important to the email client account. Since the process we've discussed above deletes the file permanently, it will also permanently delete the data across it, which would essentially never be accessed by the user because of specific reasons.

However, if you are willing to save your data for the email, the best way to approach this is by converting the existing OST file to a PST file.

This process will be covered by Stellar Converter for OST, which primarily provides an easy-to-use environment and consistency in working across the platform.

While it allows users to preview the screen with the details of the OST file, it can also cover multiple files in the conversion. This makes it a very impressive option in the market. To understand how users can convert their OST file to PST, follow the steps shown below:

Step 1: Opening Stellar Converter

Launch the tool across your computer and select the "Select Outlook OST" button across the "Home" tab on the window. A new window opens up for the selection of the file across the computer.
