Hey Nicholas,
Thanks for reaching out to the SmarterTools community. Can you please check the ticket import log? This is located in Settings->Diagnostics->log files. Please look for exceptions that will likely tell you what's going on there. You can also look in the spool in Settings->Spool->Incoming Do you see it stuck in there? What does it say?
Kind Regards,
