If a Microsoft Exchange database is backed up using the Exchange Plug-in, you can restore mailboxes, messages, and other objects from the backup.
To restore items from a Microsoft Exchange backup, you must first use Portal to expose the Exchange safeset as a shared resource. You can then use the Granular Restore for Microsoft Exchange and SQL application to find and restore mailboxes, messages and other Exchange objects.
For more information, or to obtain the Granular Restore for Microsoft Exchange and SQL application, contact your service provider.
To restore Exchange mailboxes, messages and other objects:
1. On the navigation bar, click Computers.
A grid lists available computers.
2. Find the computer with Exchange objects that you want to restore, and expand its view by clicking the computer row.
3. Click the Jobs tab.
4. Find the job with Exchange objects (e.g., messages) that you want to restore, and click Restore in the Select Action menu for the job.
The Choose What You Want to Restore dialog box appears.
5. Select Mailboxes, messages and other Exchange objects, and click Okay.
6. In the Restore dialog box, choose a safeset from which to restore.
7. In the
Encryption Password box, enter the data encryption password. To view the
password hint, click the Hint button.
8. In the Idle Time box, enter the number of minutes of inactivity after which the share should automatically stop. The value can range from 2 to 180.
9. Select or clear the Use all available bandwidth option.
10. Click Share.
The Process Details dialog box shows the status of the share process. When the share is available, the share path appears at the right side of the dialog box.
11. Click the Copy Path
to Clipboard button. 
The path to
the safeset share is now available for you to paste into the Granular Restore
application.
12. Launch the Granular Restore for Microsoft Exchange and SQL application. Paste the path to the Exchange safeset share into the Granular Restore application, and then select and restore your data. For more information, see the Granular Restore for Microsoft Exchange and SQL User Guide.
13. When you no longer need the safeset share, click Stop.
When you click Stop or the share idle time is reached, the Current Process information indicates that the share is no longer available.
