How to restrict customers to select as request participants

[Marion Hederer]

We have different service desk projects on one instance. Most of them are connected to email channels --> customer permission are set to "anyone can raise requests" --> everytime someone sends emails a customer with this mail-adresse is created. 

Problem: some of this emails (and further customers) are privat email adresses and only agents should be able to see and use them. 

How can we prevent that customers can choose this privat emails when selecting request participants --> right now if they start typing a name, they get both - the privat and the business email adress

I personally have not tried this, but worth testing out:  In the Customer Permissions in each JSD, you can select "Other customers in their organization" for "Who can customers share requests with?"  Add all users to this organization, and then users created via email will not belong to this organization.

Hi Andrea, 

this was also my first idea and I just implemented this - seems to work so far.
