Yahoo Premium
I recently upgraded to Yahoo Premium to increase my email storage space. I needed to edit and send a form to my doctor today. His receptionist received the form with my signature only. Any fields on the form that I entered information in a blank space were erased. I kept opening the PDF form on my computer and could see all content. I would upload the form to the email message, click on the icon to see the preview, and none of the content that I entered in the blank fields of the form showed in the uploaded one to my email. The form on my computer is completely filled in. I'm not sure why Yahoo Mail would delete the content of an edited PDF form that was uploaded to be sent to a recipient.
