A page that has a list of emails not linked to a case that can subsequently be linked.
Hi Rachael
If I’m understanding correctly, you could create a page which contains a list widget with your “Message” object which is being used for your emails.
Then you could create a subset from the “Message” object to your “Case” object and only show ones where the relationship does not exist.
This would list all “Message” object records which do not have a relationship to any “Case”, and you could then build the logic to link these emails back to relevant cases.
