I am using iPhone 5 with iOS6.0.1 native mail app.  Emails with winmail.dat attachments (probably sent from Outlook with RTF) do not forward when the attachment is included, they do not show up in the sent items and there are no error messages saying the sending failed.  The body text of the email is legible on the iPhone.  The winmail.dat is actually a PDF.  Does anyone have any idea on why forwarding this email including the attachement does not work?  I can forward the email without including the attachement without any problems.



iPhone 5, iOS 6.0.1

    What is the file size of winmail.dat?

    This is probably becuase ".dat" files are not supported as mail attatchements in the iOS:

    I was having problems receiving PDF attachments in e-mail on my iPhone 5 with iOS 6.0.2.

    PDF attachments would arrive as winmail.dat files.


    Until a couple of months ago, I had been successfully receiving PDF attachments for several years (iPhone 3, 4 and 5).


    I had one of the e-mail senders delete my contact information in their Outlook address book and the problem was fixed for any new e-mails that person sent to me (not the previous emails).


    I saw this solution over in the OS X forum.
