Step-by-Step Guide to Convert OST to PST: Free & Pro Methods

Requirement to Convert Outlook OST File to PST

OST (Offline Storage Table) is created when Outlook connects with the Exchange/IMAP server and allows users to work offline. It creates a copy of the cache mailbox data and syncs automatically when the connection is restored online.

On the other hand, PST (Personal Storage Table) is a quite portable format that stores the entire mailbox data for all sorts of tasks. This includes backup, archiving, and migration.

Furthermore, the top reasons to convert OST file to PST are:

• Recovery of file data from inaccessible or legacy Outlook profiles.
• Migrating emails between the system and Office 365 tenant accounts.
• Backing up of OST mailboxes before the Exchange is decommissioned.
• Accessing old OST file data without actually configuring the original account.
• Migrate data between multiple Outlook profiles and recover in case of loss.
• Archive large OST file data into smaller sets for efficient and proper access.
