I run RT 4.4.1 with a number of queues. These queues have a custom field in common. I’ve changed $DefaultSearchResultFormat to include this field but this no longer works (I’ve created a new user to test this).
If we go to a user’s Settings → Search options, the custom fields are not available on the field list.
Is there a way to add this custom field to the display columns?
Yes, I had this SeeCustomField set for Privileged group and, when I saw your reply, I tested also with Everyone group, same result, no custom fields on the Search Preferences.
