What is the difference between OST and PST?

Accepted Answer

An OST (Offline Storage Table) file is a local copy of your mailbox that is stored on your device and is created when the Cached Exchange mode is enabled in Outlook. An OST file allows you to access the email data when you are not connected to the Exchange server and it is synchronized with the server when a connection is established. The synchronization ensures that all changes made to the OST file are reflected in the Exchange mailbox. On the other hand, a PST (Personal Storage Table) file is a separate file that is used to store and backup email data, contacts, calendar items, and other Outlook data. PST files are stored on your local device and can be easily backed up, transferred, or imported to another device. In a nutshell, OST files are used to provide offline access to Exchange mailbox data, while PST files are used for archiving and backup purposes.
