Got two exchange servers exhibiting the same behavior when installing the agent. It looks like when it registers it sees the status but when I try to do a list resources it tells me there is a problem with the agent:
Doing the "Reinstall plug-in" doesn't seem to do anything and or fails to reinstall. These are servers in a lab enclave but my thinking is if port 17778 is working it wouldn't say "connected" in the connection status, and it wouldn't see all the other agents as "installed"? I've seen others have problems with this plugin as well with no solutions and I'm starting to fear the worst...
