I have installed one Windows2008 Domain for Messaging.While I am trying to do /forestprep in the domain it shows too many errors.Can anybody tell Echange 2003 will work in windows2008.If it is supporting how can i solve this issue.? is it possible to use Windows2008 as forest root and Windows2003 as Exchange server ? error showing while installing in windows2008 domain Facility: Win32 ID no: c007007e Microsoft Exchange Setup

Exchange 2003 is not supported and cannot be installed on Windows 2008. Having Windows 2008 forest should be fine! http://msexchangeteam.com/archive/2007/08/16/446709.aspx Thank you, Ibrahim Benna MCSA+Messaging, MCSE+Messaging, MCT, MVP "Did you backup your Information Store Today?!"
