I'm testing the service desk plus system and I got stuck while I was trying to create an incident template that auto fill the field "Email-Id(s) to Notify" 

I have a requirement that a distribution email from our Exchange server must be auto-filled on create any indecent\request that uses this template, moreover the requested can't edit it but he can view it.

I tried to configure the Notifications Rules but the distribution group wasn't showing either

your kind support is highly appreciated.

Thank you.
