Rejoin dead Exchange problem

Question

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.

Answer 1

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.

Thanks Andy. It should be the answer where I need.
