Hi I have an Exchange 2003 sp2 running on Windows 2000 Server SP4. The Server needs a rebuild. Another server will be used whilst the other one is off line for its rebuild. Eventually the original server will be put back into operation. What is the best practice to go about this: Do I add the new server to the Exchange Admin Group and copy the Exchange files across and use recovery storage procedure. or Copy the Mailbox to another server using KB821829. Any help greatfully received
