Email Collector only available to administrator

Hi.
We have been trialling dolibarr and are about to go live with it. We use Email Collector to create tickets but have found that only administrators can access Email Collector. I have created a short cut on the menu but non administrators get “access denied” when using it. There is no where to add user permissions for this module.

Am I missing something? I dont mind digging in the code a bit to “open up” access if anyone can point me in the right direction.

Thanks Nick
