Hi Team,
We have an in house application server which is integrated with our exchange 2013 server, we have added the IP of the application server on receive connector to send emails , recently for some maintenance work we had to restart the Microsoft exchange transport service couple of times on the mailbox server where the receive connector is created.
After restarting the service we have found lot of duplicate emails are being generated, not sure if it is because of the exchange server or the application,i feel its because of the exchange server as we paused and restarted the transport service couple of times after which this issue started.
