I have Two site
A (Exchange.com )and B (Test.com)
Both Sites have one DC and 1 Exchange Server with Mailbox (with 1 Database), Cas and Hub role
Site B Got down due to Server failure
We do have DB backup of Site B we want it to mount it to Site A as per the company requirement
I Restore the DB and Bring it to Clean shutdown state and Created a RDB with that Database
However its giving error while mounting that RDB
