How can I easily convert OST file to PST file?

You can easily convert OST file to PST file using a dependable MSOutlookhelp OST to PST converter tool. These tools are designed to extract emails, contacts, calendars, tasks, and other mailbox items from an OST file—even if it is orphaned or inaccessible—and save them into a PST format that opens directly in Microsoft Outlook.

Simply install the software, add your OST file using the Select File or Select Folder option, and preview your mailbox items. Then choose PST as the output format, apply optional features like removing duplicates or filtering by date, and start the conversion. Once the process finishes, you can import the resulting PST file into Outlook.

This method is quick, requires no manual configuration, and works even without Outlook installed.
