We upgraded our Exchange environment from 2003 to 2010 several months ago. Now we are trying to uninstall the 2003 servers. We are getting an error on the exchange uninstall about a routing group connector. Looking at it I assume it is there so the new servers can talk to the 2003 back end. I think it can just be deleted but I want to make sure that it will not cause any problems with our existing environment. &nbsp;I have attached a screenshot. Can I just delete it? &nbsp;<a href="https://filedb.experts-exchange.com/incoming/2011/03_w13/435922/untitled.JPG" target="_blank" title="Routing group connector (17 KB)"><img alt="Routing group connector" class="file-block lazyload" style="max-width: 384px;" data-src="https://filedb.experts-exchange.com/incoming/2011/03_w13/435922/untitled.JPG" /></a>
