Dear all,

We have two exchange servers before. One of them was down and dead. So, I had manually removed it from our AD. After several months, i have found that dead server can be restored successfully. Can i use it back to rejoin our AD and work together with our existing Exchange organisation again? Please advise, thanks.

    If you restored the server to AD and the Exchange configuration is still set for that server you can recover it:

    If not, then you have to install Exchange to it as a new install.
