Your Exchange account was removed, the mailbox was deleted, or the offline file is corrupted. Now the emails sitting in that OST file are out of reach. MailsSoftware OST to PST Converter reads the OST directly and exports its contents to a PST you can open in Outlook, or to several other formats.

Key features
Repair damaged or orphaned OST files
The tool scans corrupted, inaccessible and orphaned offline files and recovers their data. You add the file, and it builds the mailbox preview.
Preview the mailbox before you export
After scanning, you see the whole mailbox in the same folder structure as the original, so you can check the data before saving anything.
Export to PST, EML, MSG, MBOX, RTF or MHTML
PST is the main target. The same data can go to EML, MSG, MBOX, RTF, MHTML and HTML, which suits other email clients or archiving.
Split a huge OST into smaller PST files
The optional Split PST setting cuts output by size in MB or GB. That keeps each PST manageable. The vendor says it has tested an OST of 80 GB.
Export only the folders or emails you pick
You can select specific folders, subfolders or items. A mail filter finds messages by subject, To, From and date.
Keep mail properties and attachments intact
To, CC, BCC, subject, body, HTML formatting, inline images and dates are preserved. Attachments stay with their messages. Emails, contacts, calendars, tasks, notes and journals are all covered.
Who it's for
It suits you if you have an orphaned or corrupted OST after an Exchange migration or account removal. It also fits an admin who needs to hand a user's mail over as a PST. You don't need Outlook configured during conversion.
