An update on progress around Exchange 2010 address list segregation documentation
Microsoft has always provided a shared hosting whitepaper for versions exchange 2000-2007. Does this article mean that Exchange will no longer allow a custom shared hosting solution, but only the hosting setup built-in with Exchange 2010 SP1 when its release? This would be a large dissappointment, there should still be documented procedure similar to the shared hosting documents released for the other versions. Most hosting companies used MBP Hosting docs as a guideline. Most companies take the chance of not getting full support, just best effort with their own methods of hosting for their organization. Which means this will definitely go away if a setup option is all they recieve. Maybe you have an unsupported/adhoc method that can be posted so organizations get an idea how the autosetup of 2k10sp1 will prepare your environment for hosting?
