Hi<br />
<br />
We are currently running Exchange 2003. We have four routing groups.<br />
<br />
One of the routing groups is HQ, and we plan to install an Exchange 2007 server there. The other sites will remain on Exchange 2003 for a short time.<br />
<br />
I've heard when you install a 2007 server into an Exchange organisation with 2003 servers, you need to make a registry key change to ALL Exchange servers to supress link state information.<br />
<br />
Can someone confirm if this is true? If so, how would routing groups continue to work for the groups that hadn't moved to 2007 yet?
