In offline (Cached Exchange) mode, Microsoft Outlook saves all Exchange mailbox data in a local file named OST file. When the Exchange connection is re-established, the changes made by the user in offline mode are updated to the server mailbox. Exchange Server crashes and disasters, Exchange mailbox deletions, and other events have no effect on the OST file because it is stored on the user’s computer. As a result, in the event of a disaster, Exchange administrators and end-users can use OST files to restore user mailbox data through manual methods for converting an OST file to a PST File or you can go with the Proficient OST to PST converter Software.
Here are some Scenarios in which Converting an OST File to a PST File is Extremely Beneficial:
A small number of Exchange mailboxes are removed from the server.
Do you need to back up a couple of Exchange mailboxes?
An Exchange user wants to rebuild his OST file, but there is some data in the OST file that has not been saved.
Due to Exchange corruption, server crash, and other factors, EDB files are inaccessible, and users require immediate access to their emails.
If you can log in to Outlook with the same Exchange profile, you can convert any OST file to PST using one of several methods. Here are some native methods for converting OST to PST:
- Data from your mailbox can be exported to a PST file.

You can save the items from the OST file in a separate PST file by enabling the Auto Archive method in Outlook. This method aids in keeping the size of your mailbox under control.
