iPhone does not display attachment in email
Symptoms
When receiving email messages with attachments (Word, Excel, or PDF files) represented by the paperclip icon, the attachment may not be displayed when the message is opened. Instead, a plain text version of the message is received and contains an attachment named Winmail.dat which cannot be viewed or opened.
Products Affected
iPhone
Resolution
This happens when the email message is composed in RTF (Rich Text Format) with attachments. If it doesn't, then the sender of the email message will need to compose the email message in either plain text or HTML so that it can be viewed on the iPhone. For more information and for steps to configure Outlook to send Plain Text or HTML see the following Microsoft KB document: How e-mail message formats affect Internet e-mail messages in Outlook.
