Outlook File Saving Formats ( OST ) and ( PST )

OST Outlook File:-

An OST file, also known as an Offline Storage Table, is a file format used by Microsoft Outlook that saves a replicated version of the mailbox data on a user’s computer. This enables users the ability to retrieve their emails, contacts, and calendar events without the presence of internet connections.

As soon as the connection has been re-established, all the updates made on the account while in the offline mode are promptly updated in the Exchange server to maintain uniformity in the records.

OST files are especially useful in cases where there is an unstable internet connection because they enable the users to continue working without interruptions. They are made as soon as the use of Outlook involves linking to the Exchange account which allows access to important data even when the user is not online.

PST Outlook File:-

In detail, a PST file (Personal Storage Table) is a file format that Microsoft Outlook uses to monitor when storing emails, contacts, calendars, and other files in a user’s computer’s hard drive.

PST files unlike OST files which are mainly designed to facilitate the users with the local access to their respective mailboxes do give the user an option to backup and archive his or her Outlook’s data. This revocation strategy proves to be very vital, especially in the case of POP and IMAP accounts whereby the users are allowed to go offline and still access their information.

PST files are created by users and play a crucial role when switching between or among email clients. They are, however, not good when not managed properly as they can get damaged or become a threat to security.
