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 third-party tools. 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 third-party tools 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.

Efficient methods to convert OST2PST

Using the AutoArchive Settings

AutoArchive in MS Outlook is a feature offered by MS Outlook to help users convert their OST files to PST. With this, you can convert all kinds of mailbox items to PST excluding contacts. Follow the simple procedure to convert files using archive:
