I am considering starting a hosted exchange service for my clients, where they rent mailboxes on my exchange cluster.
I know there are many companies that offer this already. My biggest complaint is that for businesses that have a Windows AD infrastructure already, there has never been a relation between that and the hosted exchange mailboxes, so they are managing separate userlists, passwords, etc.
Furthermore, migration from an in-house exchange to a hosted requires reconfiguring outlook, moving PST's, etc.
I believe microsoft's BPOS does offer AD integration...
What i'd like to do is have hosted exchange (in my datacenter) which then, for each "customer" it can sync to their AD. Of course i'd need to install some type of connector or open firewall/LDAP rules, but my goals include:
single user creation/passwords, etc
ability to migrate easily from in-house to hosted
anyone know any way to do this? maybe an add-on app?
