We have several support desk projects for our direct customers, that are only accessible if we create an account for the customer user. (access is set to Customers added to this service project only by agents and admins).
Next to that we have several end-customer projects where end-customers can create tickets by sending a mail to a custom mail address, without an account (access is set to Allow customers to create accounts in the global customer permission settings). These end-customers will only communicate through the e-mail channel, not the portal. Jira will make end customer accounts for each mail address that opens a ticket. Without this setting unknown users cannot create tickets via e-mail.
We want to keep the two types of customers completely separate, so we need to completely hide the end-customer projects from the portal.
The end-customer portal can be hidden from the main page of the portal, so that is great to reduce access to the portal, but the direct customers can still see the issue statuses when they look for tickets under the requests button and still see the portal when searching with the correct keywords.
Is there a way to keep the ability to open tickets via e-mail, but completely shut out the portal for the end-customer projects?
I could not find a solution for it.
The permission scheme unfortunately does not offer a solution as the project is then still visible for the direct customers...
