vsin11 -> How to recover/extract the mailbox from the Recovery Storage Group (2.Apr.2007 7:41:17 AM)
The Recovery Storage Group is identified by the msExchRestore Attribute. The msExchRestore = TRUE property tells us if a database is a recovery database.
As such we cannot directly connect the mailbox from the RSG to user direcly. We have to modify this msExchRestore Attribute and make its value to Not Set so that it cannot be identified as RSG and we can connect the mailbox to the user.
The Action plan here is that we will create a test user account without the mailbox, modify the msExchRestore Attribute by using ADSI Edit and the connect the mailbox of Vinay Dev Jhari from RSG to this test user account. Then we open the mailbox from the Outlook and export it to PST.
Following are the detailed steps that need to be followed:
1. Create the test user account. Do not create a mailbox for the user account.
2. Reset the MsExchRestore attribute on both the Recovery Storage Group, and the recovered mailbox store using Adsiedit:
Expand the Configuration Container node, and then browse the hierarchy to:
CN=Administrative Group Name
CN=Recovery Storage Group
Right click for Properties on the Recovery Storage Group, ensure that the checkbox for "Show Optional Attributes" is checked. Scroll down to the "MsExchRestore" attribute. Double- click the MsExchRestore attribute and check the
<Not Set> parameter. Click OK, Apply, and OK to exit the properties pane.
Right click the "CN=MailBox Store(ServerName) under the Recovery Storage Group, and select Properties. Ensure that the checkbox for "Show Optional Attributes" is checked. Scroll down to the "MsExchRestore" attribute. Double-click the MsExchRestore attribute and check the <Not Set> parameter. Click OK, Apply, and OK to exit the properties pane.
Close the AdsiEdit mmc
3. In Exchange System Manager select the Recovery Storage Group, right click and select Refresh. Expand the Recovery Storage Group, then the mailbox store.
4. Select "Mailboxes" under the Mailbox Store, then right click the mailbox to be recovered, and select "Reconnect". The applet "Select a New User for this Mailbox" applet will appear. Enter the alias of the user you wish to associate with the recovered mailbox into the "Enter the Object Name to select" data entry field, the click "Check Name". The alias of the user should be resolved to the full display name. Click OK. You will see a pop-up stating "The operation has completed successfully".
