How can I enable the option for external customers to share their cases with their team members?

I would like to enable the option for external customers to be able to share their cases with their team members - from the portal in JSM On-Prem. Right now I can not add any other users, groups or add an email address.

Please check the image attached.

Hi @syee ,

To enable case sharing for customers in JSM, you'll need to configure the customer permissions in your project settings. Here's how you can do it:

Navigate to Project Settings > Customer Permissions > Configure sharing options > Save changes.

I hope this will help!

Hello Syee, 

Have you looked at your customer sharing permissions?
