1 exchange server serving 7 domains?

I have a client, who has about 7 different and seperate domains within the same company.  These domains do not trust each other, and won't have a trust for some time (we want to go to a single AD, but can't for a year or so).

We now want to roll out exchange, with a single message store serving all 7 different and distinct domains.

Any idea if this is possible?


I'm thinking no, as I'll have a single exchange server cluster, that will need to be accessed by 7 domains / 7 ADs

It is possible, but will involve a lot of management work.
The domain with Exchange in it would need to have accounts for every user across all of the domains. The users would then need to maintain two sets of user names and passwords. When Outlook is started they would have to authenticate to the domain with Exchange installed in it.

It is just like a hosted Exchange deployment.
