Error when sending CAB approval with attachments

Error when sending CAB approval with attachments

When attempting to send the approval email from change management, I get the following error if the approval has any attachments "Email Sending failed for the following user(s) :" Then lists the users.

If there is no attachments it works as expected and sends the email to the approvers
