Hello, we had a case the other day where one of the auto notifications did not get sent out. In the conversation area with the auto notification checked, the notification was not there. It seems to be a one off as other cases with the same template are working fine both before and after.

But I still need to inform my end users on what happened as the notification was a call for information. I have checked the system logs, the mailbox and even ran a message trace in Office 365. Are there any other areas that I can check to see what really happened? I did notice that the Data archiving started up at the same time that the case was submitted, but I would hope that that is not the cause. 

Thank you.
