We are having Exchange 2013 environment with 2 servers. (DAG configured). Everything was working fine until from last 10 days the mail flow stops suddenly. During this time if i login to both server to the check the Queue Viewer, i am getting an error in the mmc as below on both servers.
"FX:{714FA079-DC14-470f-851C-B7EAAA4177C1} Type is not resolved for member Microsoft.Exchange.Configuration"
The mail flow resumes only after restarting both servers.
During this time all the services are running, i am able to access owa and also outlook connection is working fine.
Can anyone have suggestion regarding this issue?
