HI All, I am stuck in a very difficult Situation . I have Installed Exchange 2007 Standard Edition 64bit After installation i configured all my Organisation Mailboxs and all . Than i started instalaltion of Exhcange SP1 which is been released .After installation of SP1 i was shocked and surprised that the whole exchange 2007 was crashed means the exchange management console disappeared ,in add remove programs i cant see any thing by the name exhcange 2007 etc. Kinly any one help me out and let me what is the Cause due to which my exchange crashed .Also is exchange Sp1 is not stable. Kindly get back PLZ.

Did you read the relase notes for Exchange 2007 SP1 before upgrading? Did you knew that SP1 also includes RTM?, so in the future you dont need to install RTM and then apply SP. just install from SP1 media direct.

Hi but i am having already installed Exchange 2007 RTm and how come i upgrade it to Exchange SP1 ? Can u send the link only which contains SP1 and can update on my existing exchange2007 RTM as my exchange 2007 RTm is a live server and i cant play around it.
