Hi all, Is it possible to have multiple domains in a single forest all pulling mail from Exchange 2007? Where the domains in question are NOT in a Parent\Child domain scenario I have read the following "Planning for a Large Exchange Organization" but it didn't seem to answer my questions. http://technet.microsoft.com/en-us/library/bb123567.aspx Its this whole process of a "one exchange organization" limitation that I don't quite understand. Thanks

One exchange org per forest is the rule, it doesn't matter how many 'tree roots' you have in the forest, one exchange 2007 deployment will be fine as long as its just the one forest.

Thanks Knightly, thats good to hear!
