ALL: Error Message: "Your workflow approval message was not processed. You are not authorized to update the referenced object."
An error stating, "Your workflow approval message was not processed. You are not authorized to update the referenced object," may occur when replying to an approval email. This error happens if the user replies from an email address that does not match the one specified in their Salesforce user record. To resolve this, the user must ensure their reply email address is identical to the email address listed in their Salesforce user profile. This can occur when using an email alias, a forwarded address, or after a company domain name change.
