Is that correct ? please help me in that . The second questions is :- what will happen to the old data base ( Prive1.edb ) & ( Priv1.stm ) , when I install the new exchange , is the old one deleted or what happen ? or why I am saying to it that , this Database can be over right ? Can any one help me to clear this from my head ? Thanks
