Is there any way to prevent customer accounts from inviting new customer accounts?

Question

We have a need to still allow customers open access to create their own accounts via the portal site, however we've run across perhaps some unintended functionality via the "share" option within the portal view of our tickets.

The "Share With" feature allows customers to manually enter an email address and if it doesn’t match an existing customer, Jira will invite them as a new customer.  We would prefer that it doesn't do this, but the only apparent settings available to lock this down would effectively prevent the open access needed for customers to create their own accounts.

You could control it a little bit by modifying your allowlist/blocklist for specific domains, but that would be sort of a never ending battle.

Yes, if you are allowing customers to share a request with any email addresses then you would also have to invite them to your instance so they can see the request. It's sort of a catch 22 moment...

Thanks for your reply Joseph,

We've referenced the customer sharing settings, but specifically have an issue with "Sharing with an email address that doesn’t match an existing customer will invite them as a new customer."

We would like to prevent them from triggering an invite.
