I have a problem sending email attachments from my Outlook account to various Yahoo email accounts. The email arrives fine, but the attachments are somehow corrupted into something that cannot be opened. Below is a screen shot of the message I get when I attempt to download a PDF file, though the same happens with Word attachments. And there is no "open" option available. It seems as though all the attachments are renamed to some version of "di-mail.ymail.com":

Please help.
Thanks,
Phil
