Hi,I am going for a hosted solution with Exchange 2007 over 2008 domain. The only issue is how I am going to gide GALs from each other's GAL.We used to do this in exch2003 with 2003 domain by playing with some AD attributes. Now i have read that its not supported with exch 2007. The only Solution is HMC. Now the question is 1. Is HMC going to segregate the GALs on its own or do i need to configure it?2. Is HMC also going to work as control panel for my end user or i need to buy some other cotrol panels (host control or dot net panel).3. Is there a step by step deployyment guide for HMC?Regards,rajRaj

Hi Rajesh, Refer below white paper to configure address list segregation in Exchange 2007 environment without HMC. White Paper: Configuring Virtual Organizations and Address List Segregation in Exchange 2007 http:// technet.microsoft.com/en-us/library/bb936719.aspx Suggest you to use HMC forum if you have any questions regarding to it. Microsoft Solution for Hosted Exchange - Forum http://forums.asp.net/159.aspx TechNet Documentation for HMC deployment...

Thanks Amit... will try the HMC forum.I have already seen that GAL segregation link and its just impossible to provision new customers coming in on hosted exchange with that and also the scripts are very crude and probably not designed for production on a huge infrastructure. Probably its good for testing or from theortical point of view.Thanks,RajnishRaj
