Unable to restore single email
I am having backup of Exhange, and when I am going to restore single email using restore, it shows me mailbox even email over there, but when I select email to restore, it starts staging but take many hours and ended at failure.
Can anyone help me, what could be the reasons? and what are the concerns which I should keep in mind while taking restore. "for reference GRT is enable and data is backed up on tape"
Waiting for quick response.
