I have an issue with one user on our system.
The user is connected to Dynamic CRM and at the end of the month aprox 300 emails are sent at the same time.
The problem is that when certain limit is reached, the system no longer process the queue.
I first thought that it is related to maxrecipientlimit, but there is one recipient per message, so this is not the case.
Can you guys help me with this?
