Hi

We have three sites running EX2010 with MBX,Hub and CAS at all three. One site is internet facing via TMG2010.

We have now deployed EX2013 and all appears to be working OK, however we are receiving health report issues with the CAS at all three sites.

The FrontEndTransport reports as failed but I am unable to see why. We also get an error under the InvokeNowResult that implies that the OnPremisesInboundProxyMonitor could not be found.

Any help much appreciated!
