Unsubscribe from Inbound Email Action Stopped Processing because of Email FormatIssue The 'Unsubscribe from' Inbound Email Action stopped processing and you could see the following warning in the email logs: 2024-09-11 12:15:20 Warning An unsubscribe request with an invalid ServiceNow unsubscribe ID2024-09-11 12:15:20 Information Unsubscribe from Notification : did not create or update cmn_notif_message using currentReleaseAll ReleasesCauseThe root cause is that the body of the email is encoded using charset="us-ascii". According to KB0724439, ServiceNow processes emails in ascii and utf-8 as they are. Therefore, the issue happens with the double-quote, and the system could not properly read the value from the token object, which finally caused the 'Unsubscribe from' Inbound Email Action to throw an error.ResolutionIf the issue is happening for only one user: change the settings in your email client to send emails as utf-8 If the issue is happening for all users, either contact your email admin to ensure they send emails to ServiceNow as utf-8 or you create a on-before business rule on your email table to convert ascii to UTF-8.
