An OST – Offline Storage Table– file stores a synchronized copy of your Outlook mailbox items on the local storage. This file allows you to access your mail items – emails, calendars, contacts, etc. – even without an internet or server connection.

OST file is linked to the profile in which it is created. This means you cannot open or import it directly into another profile or account. Moreover, if your OST file becomes inaccessible or orphaned, you cannot access the mail items.

In such cases, the only option is to convert the OST file into PST – a portable Outlook data file format that you can easily open or import into any Outlook profile or account.
