Hi <br />
<br />
I need to host mail for multiple forest on 1 exchange instance. &nbsp;The current exchange is within a forest curently hosting mail. &nbsp;Our exchange server is Exchange 2010<br />
We have F5s for our load balancing.<br />
<br />
We want full MAPI services. (calendar sharing GAL etc.) <br />
<br />
We have several Forest that have no trust setup.<br />
<br />
The back story here is we bought a few companies and nothing has been done to integrate the companies. &nbsp;A couple of the companies exchange servers are ready to die. &nbsp;Instead of buying new servers they want the head office to host the mail. &nbsp;But they want it so it’s the same as they currently have or better. &nbsp;Better would be faster 1 GAL to rule them all etc. <br />
<br />
Basically using something like POP 3 is not an option. <br />
<br />
I am open to all ideas here.<br />
We can do just about anything here within reason. &nbsp;VPNs, limited trusts etc.
