Converting an OST File to PST format in MS Outlook can be done by the OST to PST Converter Tool. When a user wants to transfer mailbox details for moving the details to a new profile or if the original profile does not connect to the mailbox, this tool is made available for the user. A number of the versions of the software provide functionalities such as being able to preview the items that need to be converted prior to the conversion process taking place, conversion of only selected items, deletion of duplicate items in the mailbox, and basic repair of files. Other output file types include EML, MBOX, MSG, and HTML. The Converter produces file types for email backup, email recovery, and email movement, as the Converter will be usable on multiple MS Windows and Microsoft Outlook versions.
