Stellar Converter For OST – Product Review

MS Outlook is a popular email client used by small, medium, and large enterprises across the globe.  When Outlook is configured with an Exchange, Office365, Outlook.com, or IMAP email account or profile, it creates a local offline Outlook data file (OST).

The OST file stores a synchronized copy of mailbox data, such as emails, attachments, contacts, notes, etc. It allows Outlook users to access their mail items even without a mail server or when the system is offline.

However, unlike the PST Outlook data file, the OST file cannot be imported or accessed from other Outlook profiles as it is encrypted by default with MAPIEntryID GUID. It can be accessed through an authorized MAPI profile only.

In such cases, where you cannot access OST mail items or require to access or migrate mail items from an orphaned or inaccessible OST file to a different Outlook profile, live Exchange, or Office 365 account, you can use an OST to PST converter, such as Stellar Converter for OST.
