What is OST File and PST File?

OST File: OST file is an Offline Storage File that is created at client end when we set a MS Exchange work environment. These files are used to keep a local copy of your Exchange mailbox data. Users can perform tasks at client end being offline and the Mails, Notes, Contacts, Tasks and Personal Folders are synchronized with the Server when a connection is available next time to network. Although, we can access Exchange mailbox from other browsers directly (OWA) now but OST file is created in MS Outlook application only..
PST File: PST file or the Personal Storage Table file also contains the same items as contained in the OST file and located at same path where OST is located, but OST file is created in the Exchange Server-Client environment and PST file is created while there is no Exchange Server in the center.

How to Export OST to PST?

We know that an OST file contains a copy of the mailbox data but it is always accessible when a healthy connection is established to the Server. If the connection is available but the Server is not responding due to corruption or loss of data or non-accessible directory services, then OST files get inaccessible for local MS Outlook application too and we can not convert OST File to PST also. So you need a third-party OST to PST Conversion tool for OST recovery at that time.
