  • 發行項

In this post we will discuss how to use a recovery storage group in SBS 2008 to restore two lost important messages.

Our test user has two messages in his inbox that are important to him.

Somehow these two messages got deleted and for some reason we are unable to recover the messages using deleted item recovery in Outlook. We have a backup made prior to the deletion of the messages so we can use a recovery storage group to restore just this one user’s mailbox.

Restore Exchange

In order to use a recovery storage group you must first restore the Exchange databases to an alternate location.

  1. To do the restore we would launch Windows Server Backup from administrative tools and click recover.

  2. Choose to recover This Server.

  3. Pick the date of the backup job that contains the missing mail messages.

Create Recovery Storage Group

Once the databases are restored, you can run the Exchange Database Recovery Management to setup a recovery storage group with the databases that were just restored.

  2. Select the Toolbox node
  3. Open the Database Recovery Manager

    Note: First Storage Group contains your Mailbox store by default in SBS 2008

How to Handle Corruption

The database may fail to mount because it is in an inconsistent state. If it fails to mount you will see a screen similar to the following:

This method will merge all of the contents of the restored mailbox and the current mailbox together. There are advanced options on the merge function that allow for selecting a date range or a specific subject. You can use these options to narrow down the amount of email to restore.

Note: Don’t forget to dismount the RSG mailbox and remove the RSG when finished.
