You may be unable to send a fax that you saved as a draft in Windows Fax and Scan if the fax does not have a cover page

This issue occurs if the following conditions are true:

• You save a fax as a draft.
• This draft does not have a cover page
• Then you send a different fax that includes a cover page.
  
  Note After you send the fax with a cover page, that cover page becomes the default cover page in Windows Fax and Scan.
• You open the draft that you saved, and you then click Send.

This issue occurs because the default cover page is automatically selected when you reopen the draft to send it. Cover page notes are saved together with the draft's cover page. For a fax that has its cover page set to (None), cover page notes for that fax do not exist. Therefore, the fax is not sent successfully.
