Sharing Outlook calendars across 2 domains?

[spherrod]

The company I work for has just acquired another company - although DNS has been set up so I can go to their premises and connect to our Exchange server there are still two domains running and each domain has it's own Exchange server.

As usual with acquisitions, there are a lot of changes taking place and now several managers in the original company are responsible for salespeople and consultants in the new company. To this end they need to see their Outlook calendars, but are currently unable to due to the Exchange servers being on seperate domains - does anyone know if there is any solution to this apart from creating one domain for the new, larger company(which is planned but not for several months)?

Any creative, innovative ideas welcome - if you need more technical information please ask and I will try and find out.

If it is just completely unfeasible until the domains are integrated it's not a major problem - sure others have seen this before though and was just wondering if anything can be done.

:beer: for reading this at least

I'm pretty sure there needs to be a 2-way, transitive trust set up b/t the two domains. You set your DC to trust "www.othercompany.com" they do the same on their DC. That is the starting point...I'm not sure where to go from there.

Oh...additionally I THINK you'll have to replicate your Global Address Lists (GAL) b/t each other before you can see each other's stuff. It's set up by IP in the server configuration tab in Exchange.

Thanks for that - I'll look into it some more with our infrastructure team
