Why my mails sent using Apple Mail have blank body in Outlook? When I send emails using Apple Mail to my colleagues (they use Outlook on Windows, various versions), it often happens that the mail looks blank and its body is split into various attachments.



Even the signature and the signature's images are moved into attachments. How can I solve that?
Looks like I found a solution. In the options screen, select Composing. Then, under When quoting text in replies or forwards select Include all of the original.
