Duplicated Automated ticket creations coming in from email, due to communication during troubleshooting

I have a problem and want to publish I here to see if anyone have this problem at their company and how did you go about addressing/fixing the problem.

The problem: As a process we are having customers send an email to the 'Helpdesk'. Once the email is receive, a helpdesk ticket is created within Service Desk Plus. But if further communication is done (via Outlook) and they decide to CC'd the 'helpdesk email', Service Desk Plus receive that email and creates another ticket...and this could be multiple tickets...depending on how much communication and how many people are Cc'ing the Helpdesk email.

Beside the obvious (not CC'ing or including the helpdesk email) in any further communication. What are options of solution to fix/prevent this problem (i.e. multiple tickets creation for one problem but due to emails being sent to the helpdesk application).

Thanks ahead of time for any input or help.

Regards,
