Outlook 2007/Exchange 2003- Share calendars Between Companies

Well,
My company had recently became partners with another company and they are on two different domains.  We want to keep the domains seperate, but the users from both domains would like to see each others Calendar Availability via MS Outlook 2007.  How do we make this happen?

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

You will need to have 2 separate profiles setup since exchange server only allows for 1 active connection to the exchange server. I know its not the best option but its a limitation of exchange.

Sorry, but that's completely wrong.  It's a limitation of Outlook that you cannot connect to more than one exchange server, you can with Outlook 2010, see my guide here:
