How to convert OST2PST file?

The OST file stores Outlook data items on the Exchange Server, and data loss may happen in case crashes occurring in the server. Also, the OST files become inaccessible during the Exchange Server maintenance, where users must wait until the process is complete. Hence, conversion of OST2PST file formats is recommended to encourage a hassle-free user experience.

The data file conversion enables users to perform operations in Outlook even in the Exchange Server crashes. It is because the PST file operates independent of the Exchange Server, doesn’t deal with the exchange server and saves storing Outlook data items locally in the local system. In addition, it seems beneficial if you want to restore deleted mailboxes from the exchange server.

You can perform the OST2PST conversion manually or using professional solutions. Manual conversion is possible only when the Exchange Server is available. You need the original Exchange profile in Outlook to do this. When Exchange is down, users must rely solely on a professional tool for OST2PST conversion.

In this article, we will cover both manual and automated methods of OST conversion. First, we will discuss the manual method and then move on to the automated solution.
