Email not creating Service Management tickets

[Raoul Kaiser]

We have a very specific set up of service desk since we are only 3 weeks into its creation for us.

• We are only allowing IT users as customers
• Our help desk email help@domain.com is a shared mailbox so it doesn't have a userid or password.
• Our service management email is ahsm@<co name>.atlassian.net
• We have forwarded our help@domain.com to ahsm@<co name>.atlassian.net

Since the emails come from everyone inside the company and our external customers if they are not part of the IT department the ticket creation gets failed per the customer access settings.

How can I allow ticket creation from any person mailing to help@domain.com without having them become a customer? We do not want anyone outside of IT to get into the system yet and maybe never want them in.

You have to declare your project as public or you have ade als person as customer or you have to bye a AddOn for that

I added that anyone (public) can create tickets but that did not work either. It all goes back go customer permissions.
