Cross Forest Exchange GRT Restore
We are trying to use the GRT restore technology for individual exchange items, which in the past has worked very well.
This time however, the Backup Exec Media Server is in Domain A and the Exchange server is in Domain B. They are actually also in different AD forests.
We have created a forest trust which has allowed us to push agents as well as backup and catalog the granular data from the Exchange Server, but when we go to do a granular recovery of an item we receive the following error:
The job failed with the following error: Unable to attach to a resource. Make sure that all selected resources exist and are online, and then try again. If the server or resource no longer exists, remove it from the selection list. Edit the selection list properties, click the View Selection Details tab, and then remove the resource.
For additional information regarding this error refer to link V-79-57344-33932"
From what I can gather we may need to create a linked mailbox which the Domain A Backup Exec service account has full access.
Has anyone successfully performed a cross forest GRT restore, and was the above required to make it happen?
Just looking for a bit of a sanity check :)
