I am currently investigating on how to incorporate Exchange 2010 in our soon-to-be multi-tenant hosting environment. We are a relatively small company focusing on the SMB market, and we want to be able to have an answer for people asking for a cloud-based solution.
Exchange 2010 in hosting mode seems to be the most logical option to achieve this, since its truly "multi-tenancy" and allows you to split everything up. The only problem I have with this is the fact that we have limited R&D time to dedicate to this and that there is almost no documentation for Exchange 2010 hosting mode. It's not possible for me to "reverse-engineer" the whole thing... I need something I can refer to.
I've asked this question to an Exchange 2010 MvP and he/she (don't want to name anybody) said to me that even the people at Redmond don't know all that much about Exchange 2010 hosting mode and that it was developed outside the "normal" Exchange team.
She also said for me to wait until SP2 so I could use ALS. As an Exchange developer, I would like to hear your point of view on this. And if you truly are in favor of using Exchange 2010 in hosting mode, could you please point me in the direction of some usable documentation to get started with this?
Thanks a bunch!
Kind regards,
Bart
