OST files, or Offline Storage Table files, are created by Microsoft Outlook to store a local copy of your mailbox data — including emails, contacts, calendars, and tasks — so you can work offline. While extremely useful, OST files are tightly bound to the Exchange server or Microsoft 365 account they were created with. If that account becomes inaccessible, the server crashes, or your profile gets corrupted, your OST file becomes completely unusable without conversion.
This is exactly why converting OST to PST is one of the most searched email recovery and migration tasks among IT professionals and everyday Outlook users alike. PST files are portable, universally compatible with all versions of Outlook, and can be opened independently without any server dependency — making them the ideal format for backup and migration purposes.
