Hi,

I have multiple 2003 AD domains. All of them are in ther own forests and there are trust between some but not others. Each AD domain has its own Exchange 2003 organisation.
I want to share Outlook calendar infomration across thes Exchange organisations.
Is this possible? If so, what broadly needs to be done?

Trusts need to be in place, but once they are the users should be able to delegate to the users in other forests.

When you say outlook calendar info, does that mean free-busy data? Or are you talking about public folders?

Thanks. I'm talking about Outlook calendar/free-busy infomrmation. I want to ensure people in the various Excgange orgs can see each others calendars. Public Folders would  be a nice extra.
