Free Convert Ost To Pst

Learning has never been so easy! Microsoft Outlook stores mailbox data in an Outlook data file.

Based on the email account type, Outlook may create an Offline Storage Table (OST) file or Personal Storage Table (PST) file to store a synchronized copy of mailbox items, such as emails, contacts, attachments, etc. on the local system. Offline Outlook OST file allows Outlook users to access their mail items even when the system is offline or the server is temporarily unavailable. However, it is encrypted by default with MAPIEntryID GUID key and thus, can't be accessed or imported into other Outlook profiles.
