Troubleshooting duplicate email notifications

If users on a watch lists are getting more than one email for each update to an incident, it may be because the people involved in the incident are replying to an email notification in which other user's names appear in the To: or CC: field. Recipients may be receiving email through their email system (Outlook, Groupwise, etc.) and through ServiceNow ITSA Suite. To stop this duplication, remove the names of other users from the email or the watch list.
