Issue: Hundreds of duplicate contacts are being created when a customer auto replies to us, instead of using an existing contact with the same name or email. We have a record creation and update rule that is supposed to only create a contact for 'unknown senders', but these senders are 'known'.

Root cause: This behavior was confirmed to be a known issue caused by a regression in the Email Address Resolution feature within Server‑Side Synchronization. The feature was globally disabled on Friday, 11/21, and customers no longer encounter this issue after that date.

Request: Please consider implementing a merge tool for those affected contacts because customer's data was affected several times last year by similar issues of incompetence where our region did not have solutions applied in a timely manner even though solutions were known.
