Stellar Converter for OST Corporate licence: the OST file no longer opens, but the emails are still inside
With the Stellar Converter for OST Corporate licence, you can manage up to 5 mailboxes.
An OST file is the local copy of the Exchange or Microsoft 365 mailbox synchronised on your PC. As long as the Outlook profile is active and the server is reachable, everything works without the user noticing. But as soon as the Exchange profile is deleted, the Microsoft 365 account is deactivated, or Outlook stops working, the OST file becomes inaccessible: it is there on the hard drive, with all its gigabytes of emails, attachments, contacts and calendars, but it cannot be opened by any other profile because it is encrypted with a key linked to the original profile.
Stellar Converter for OST Corporate solves this problem directly: it reads the inaccessible OST file, whatever the reason it won’t open, and converts its contents into a PST file that can be imported into Outlook, or into MSG, EML, RTF, HTML or PDF for immediate access without Outlook. It recovers emails, attachments, contacts, calendars, tasks, notes, journals and public folders, with the original folder structure intact. It supports orphaned OST files, large OST files up to 50 GB, encrypted files, and OSTs created by Exchange, IMAP and Microsoft 365. The Corporate version covers up to 5 mailboxes, the right size for individual users, freelancers and small IT teams handling a limited number of conversions. For organisations with more than 5 mailboxes to convert, or those requiring simultaneous batch conversion and direct export to Office 365 or Exchange Server, Stellar Converter for OST is also available in the Technician version with unlimited mailboxes.

Frequently Asked Questions about Stellar Converter for OST Corporate
- What is Stellar Converter for OST Corporate? Stellar Converter for OST Corporate is a tool for converting up to 5 inaccessible, orphaned or encrypted Microsoft Outlook OST files to PST and other formats on Windows. It recovers emails, attachments, contacts, calendars, tasks, notes and journals whilst preserving the original folder structure. It supports Outlook 2007–2021 and Microsoft 365 on Windows 7–11. For converting more than 5 mailboxes, consider the Technician version with unlimited mailboxes.
- What is an OST file and why does it become inaccessible? An OST (Offline Storage Table) file is the local copy of the Exchange, Microsoft 365 or IMAP mailbox synchronised to the PC by Outlook. It is encrypted with a key linked to the original Outlook profile: if the profile is deleted, the Exchange account is deactivated, or Outlook stops working, the OST file cannot be opened by any other profile. Stellar Converter for OST Corporate reads the OST file directly, without relying on the original profile.
- Does Stellar Converter for OST Corporate convert encrypted OST files? Yes. The software converts encrypted OST files without requiring the original Outlook profile or the Exchange password; the conversion process bypasses MAPIEntryID encryption natively.

- Does the software recover emails deleted from the OST mailbox? Yes. Stellar Converter for OST Corporate recovers deleted items from the OST mailbox – emails, contacts and appointments – that are no longer visible in Outlook, including those removed from an emptied Deleted Items folder.
- Can I convert only certain folders instead of the entire OST mailbox? Yes. The preview window allows you to select individual folders or items to include in the conversion, rather than exporting the entire mailbox.
- Does Exchange Server need to be running to use the software? No. Stellar Converter for OST Corporate works directly on the OST file on your PC, without requiring Exchange Server, Microsoft 365 or the original Outlook profile to be running or accessible.
- When should you NOT choose the Corporate version? The Corporate version covers up to 5 mailboxes: if your scenario requires the conversion of more than this, the Technician version is the natural choice without having to purchase multiple licences. Also consider Technician if you need simultaneous batch conversion, PST splitting and compaction, and direct export to Office 365 or Exchange Server. If you also need PST repair, archive merging and deduplication in a single suite, consider the Toolkit version.
