Hi there,

Will this new functionality: Disabled Ref Id and New Threading Behavior for Email-To-Case (https://help.salesforce.com/articleView?id=000355168&language=en_US&mode=1&type=1)

allow one case to be created when a user emails multiple email addresses that have been set up as an email-to-case?

Currently, a case is created for each email-to-case address resulting in duplicates and a bad user experience when multiple users respond to the same query.

 If not, is there potentially another declarative solution that only creates one case when multiple email-to-case addresses have been cc'd?
