A major update has been implemented that addresses the behaviour of emails when they arrive in ServiceNow.  This addresses some of the undesired behaviour (e.g. FWD: emails) and is intended to improve some behaviour to reduce the overheads on teams by targeting things such as ticket duplications.

Below is a summary of these changes, including the previous behaviour for comparison:

New Behaviour Previous Behaviour
All emails to ServiceNow with no reference to existing ticket to create New Call All emails create a Call except FW:/FWD: (New Incident)
All emails referencing existing Active tickets are attached to the ticket as updates Emails prefixed RE: update existing ticket.  Emails prefixed FW:/FWD: (New Incident) or no prefix (New Call) do not.
Emails to on hold tickets should update the ticket and not take it off hold (unless email is from Caller and not Out Of Offices (OOOs)) All emails to on hold tickets take the ticket off hold
Emails to Resolved tickets should update ticket (apart from “Re-Open” request) As desired (apart from FW:/FWD: emails)
Emails to Closed tickets should create new call for triage (apart from “Re-Open” request) As desired (apart from FW:/FWD: emails)
OOOs should be ignored unless they are received from the Caller (Update ticket) OOOs are mostly treated as new emails/replies (i.e. create new Call/Incident and update existing tickets)
