Super, thank you.
Given that a go. Got an email but not the one I was expecting.
McAfee Transport Routing Agent registration failed on '02/04/2016 17:26:23'.
1. McAfee Transport Routing Agent registration failed.
2. Register the McAfee Transport Routing Agent manually.
3. Please contact McAfee Technical Support.
I know it has yesterdays date. That is because I tried that change after seeing it somewhere else and discounted it because of the above error.
Not sure - the info in the case from MER goes only to about 14:30 yesterday and the logs were taken just around 10AM - so have nothing for that time.
Was there a service restart of MSME or Exchange Transport??
Anything else around that time in app evt log or msme product log??
Interestingly after doing a second test I didn't get the error email, also still not getting the notification email. Very strange.
I'm uploading new logs at the minute.
