I searched the site but cant find anything definitive, I have exchange 2003 runniing in an active passive back end with two load-balanced front ends. we currently have bes 4.0 with about 75 users and a cold standby with active passive back-end SQL. my question is can another exchange organization in a different forest within our domain take advantage of that same bes server?

love the site, glad to be a part of it.

I'm pretty sure the answer is no.

I'm also moving this thread to the BESAdmin section where you're likely to get more hits off the nature of question you're asking.

thanks

The answer is no.

The Exchange organization is an Exchange barrier that BES cannot cross. The Forest however can be crossed.
