Hello, has your email address changed? You have to "authorize" email addresses to send faxes (you can add as many as 5 email addresses).

To do this, go to Settings > My Settings > Outbound Fax Settings and find the "Email addresses permitted to send faxes:" field at the bottom.

It is the winmail.dat attachment that is causing it to fail.
