How would I segregate and setup exchange for hosting multiple companies ?

Hi All,

I’m toying with the idea of putting an exchange server into a data centre to provide exchange email to a number of companies, basically we support many companies and I’d like to have one exchange server for all the companies instead of an exchange server at each site.

So my main question is how? the network connectivity will be provided by VPN, so my question is how do I setup / segregate exchange for each company?

Each company would require shared calendar and also one public folder and a global address book each.

Any thoughts would be greatly appreciated.

Someone can correct me but I don't think what you are trying to achive above is possible.

I will look into it further but I don't think you can have more than one exchnage environment running on an exchange server.
It's perfectly possible and used by loads of hosting companies.

There are excellent articles.

I would advise against the VPN route if all you will be doing is hosting mail.  If you are using Exchange 2003, you could require your client to use either OWA or Outlook 2003 with RPC over HTTPs or if neither are appropriate IMAP or POP3, which will prevent them from using shared calendars, etc..., but then, as you can see, you're immediately offering a tiered service with, obviously, different costs.

This would negate the need for a VPN, just some kind of firewall to protect their site.
