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.
