Is there anything to read up on how to setup my own Exchange2007 hosted environment?I want to host multiple email domains for multiple external companies.All i've seen are links to Microsoft's own hosted environment to sign up for.Any help appreciated,Craig

The biggest trick is multiple GAL's and user self-provisioning..its pretty similar to doing it with 03..ms had a whitepaper you should be able to find on technet on building a hosted exchange environment. I've done it a few times. not too hard.

Thanks for the reply! Do you mind pointing me to a whitepaper, I can't see to find anything on it? Thanks!

keep searching...its out there...i'm sure the existing providers are all on the top of the search lists...just try searching in technet...i'd have to do the same search, so since you are the one who needs it, i'm not going to do the work for you :-)
