This is in a test enviroment so its not critical. I accidently deleted the server from with Exchange System Manager - Administrative Groups - Server folder. Do I need to reinstall this to get it back or is there an easier way?
It should have asked if I was sure, never did very dangerous.
It really should have asked you to confirm deleting the server, you sure you didn't get a confirmation?
The easiest way is to reinstall, otherwise you'd have to do an authoritative restore in AD and a system state restore on the server from before the deletion to get back to how it was.
