Hello: My question is a whether the following is Possible and if so, How? I have a SBS 2003 running Exchange 2003 on one domain. I have a 2008 server running Exchange 2007 on another domain. Currently, I have a bi-directional trust between the two domains in AD. Is it possible to integrate the two Exchange servers together while maintaining the separate domains so that the Exchange servers can share their databases and do all the wonderful things multilple Exchange servers are capable of doing when on the same domain? In the end, for example, I would like the functionality of a user on one domain to be able to share calendars with a user on the other domain. Thanks in Advance, Adam

Hi, if you have a two-way trust created between domains and email connectors configured correctly it should be possible. Also read this article maybe it could help you more.

Hi Adam, Please also notes: "Although you can synchronize free/busy information across forests and use it to schedule meetings, you cannot use the Open Other User's Folder feature in Microsoft Office Outlook to view the calendar details for a user in another forest."
