Disabled Ref Id and New Threading Behavior for Email-To-Case
Starting with the Winter ‘21 release, all new orgs default to the new threading behavior and Email-to-Case no longer supports string-based threading. The Release Update, Disable Ref ID and Transition to New Email Threading Behavior, lets admins of existing orgs turn the new threading behavior on or off until the update is auto-enforced with the Summer ’21 release.
Existing orgs continue to to use RefID as the main criterion for matching emails until admins enable the new threading behavior. When the new threading behavior is enabled, Email-to-Case won’t insert Ref ID for outbound emails, and ignores the Ref ID from incoming emails for matching.
