Occasionally we have an issue where email notifications are not being sent, for no obvioius reason. i.e. All the Business Rule parameters present and correct.  It seems to happen in small groups, usually very close together in a 10-15 minute window.

Can anyone explain the process of how FSM interacts with the Email Exchange server, and if the messages are held in a queue in any way? or logged anywhere we can investigate? I know from experience that tjhe notifications dont appear in the Notification Log until they have successfully reached the Email Exchange server?

Thanks in advance
