Title says it all. I've installed 2010 CAS/HUB servers in the organization (SP1) but when I check through the 2010 EMC I don't see any of the 2007 servers (brief heart stopping moment). If I look at the 2007 EMC, the CAS servers are listed. Anything I've missed that could cause that behaviour or is it by design?

Use the Exchange 2007 EMC to manage Exchange 2007 servers.Ed Crowley MVP "There are seldom good technological solutions to behavioral problems."

yep Ed is right, the exchange console is not backwards compatible, you will need to use the relevant version of the tools for each version of exchange. So for Ex 2007 use the Ex 2007 EMC, and for Ex 2003 use the Ex 2003 System Manager.Stew
