hi,

Its a strange communication error that I'm having here, though there are no service outages observed till now.

When I try to test-servicehealth from any HUB server to any Edge server, it always says some error (refer the error below), but the services are all running perfectly fine. even restarting of RPC service and WMI service not helped either.

likewise when I run get-exchangeserver -server <edgeserver> | fl name,*exchangeadminversion*, this result shows exchange version is 14.2, but the actual version of Edge server is 14.3 (SP3 with RU8. 

This means the communication between my Edge server to other exchange server having some issues? or is it a conman behavior that i no need to worry?

Error message:

Couldn't get information about the Exchange services using Windows Management Instrumentation (WMI) due to error: WMI e

xception occurred on server 'Edgeserver.domain.com': The RPC server is unavailable. (Exception from HRESULT: 0x800706B

A)

I think I got an answer for this question.

The version number displayed is the one that was written to Active Directory at the time the Edge subscription was created. Because EdgeSync is a one way process, the version number does not update as you update the Edge Transport server to newer versions. If you want the version number to reflect the current value, recreate the Edge subscription
