Stellar Phoenix Mailbox Exchange Desktop is an OST File Recovery Software that's designed to convert unusable Microsoft Exchange Offline Storage Files (.OST) file to a Personal Storage File (.PST) file that can be used with Microsoft Outlook.

It recovers all components including emails, contacts, notes, and tasks. If you're not familiar with the world of OST files, an OST file is a replica of your Exchange mailbox that is locally stored on your hard drive. The OST file helps you to speed up work on your Exchange mailbox while you are logged on to the server. The OST file is a component of your exchange server account and is not usable with Microsoft Outlook mail client. In the event of an email server crash or when a mailbox account is deleted at the server, Offline Storage Files (.OST) remain on your computer. These files can be recovered including those with large attachments by embedding the information into a usable .PST file.

This is a great tool for system administrators and system maintenance technicians as it does not require any technical knowledge in rescuing OST files.
