Scenario:

You want to recover E-mails of user whose mailbox is deleted or deleted and created with same name or different name. So here is the deal as you have deleted the mailbox and created it is going to create a mailbox with different GUID. Hence the Mailbox GUID of restored mailbox and mailbox in the production is not going to match.

Resolution:

Restore mailbox store in Recovery Storage Group where user resides from backup. Now you can't merge the mailbox with production one as there Mailbox GUID doesn't match.

1. You have to make this RSG act as normal storage group so that you can connect the disconnected mailbox to different AD account. How to do that ?
   

   
   

   1. Start ADSI Edit.
      
   2. Locate the mailbox store in the Recovery Storage group. To do so, expand Configuration Container [ YourServerName . YourDomainName . YourTopLevelDomain ] , expand CN=Configuration,DC= YourDomainName ,DC= YourTopLevelDomain , expand CN=Services , expand CN=Microsoft Exchange , expand CN= YourOrganizationName , expand CN=Administrative Groups , expand CN= Your Administrative Group , where Your Administrative Group is the administrative group that contains the storage group that you want to modify), expand CN=Servers , expand CN= YourServerName , expand CN=InformationStore , and then click CN= Recovery Storage Group .
      
   3. In the right pane, right-click the database object, and then click Properties .
      
   4. In the Select which properties to view list, click Both .
      
   5. In the Select a property to view list, click MSExchRestore and clear value from TRUE.
      
   6. Also right click on Recovery storage group and then click Properties .
      
   7. In the Select which properties to view list, click Both .
      
   8. In the Select a property to view list, click MSExchRestore and clear value from TRUE.
      

These above steps will make the database in RSG act as normal store. Then mount the store in RSG and run cleanup agent. You could see all the mailboxes in the disconnected state and you can connect the mailbox to any other AD account in the organization and then use exmerge to get the data into PST and then import it to production user using EXMERGE tool
