We need to set up a hosted mail server. We want to use Exchange 2013. I have read several tech net articles about how challenging it is and how Exch 2013 is not intended for multi-tenant. I've also read about some third party software to support it, like control centers, some stuff from HP and other vendors.
So, anyway, I wanted to see that others are doing in this area. Are you doing multi-tenant exchange. IF so, how, what third party tools are you using, etc.
I'm asking more for a discussion that a question so I'll split points with those who reply.
