Exchange backup image import not granular

Hello All,

I am trying to import an exchange backup image which belonged to a different NetBackup server. The image which was imported was backed up on a basic disk storage unit(basically a high capacity USB disk). After the import finished I am unable to see granular items for recovery. I can only see the Information store and the SG underneath it. Anything I can do see granular items?

We dont have access to original NBU server.

Thanks and Regards..
