adamjrberry Is the email assigned to a department? Do you have access to that department to view the mail?
Do you see the ticket records in the database?
It does not appear that you actually answered the questions.
Did you migrate recently?
If you are getting an email saying that the ticket was created... then it was created. It could be in an old system if you migrated recently, or it is in the new system and you do not have access to it.
Look at your ost_ticket table. see the dept_id and see if your Agent account has access to that department.
