Blank forwarded email message

Does the image have any kind of icon, graphical image, clip art, etc. as the first thing in the contents of the e-mail? If the answer is yes, then you need to use Word Mail to view that document.

Whenever you have any kind of a diagram/picture/graphic/logo in the first position (upper left corner or top center) of a document, some of the users will not be able to open the document with Outlook.

In order to open these particular documents, they need to go to Compose --> Word Mail Options --> highlight Email --> and uncheck the box at the bottom from "set as default template" --> then check "enable Word as e-mail editor." Then they need to click CLOSE and should be able to open these documents thereafter.

As far as I can tell it is because of the graphical image being the first thing encountered.

Here are a couple of suggestions:
Does the user have IE6 Beta installed? There was a problem that was resolved in the released version.

Perhaps the email receiver has a white font on white background set; Click into message body and do shift+control+end - any text highlighted?
Also, is the email blank when forwarded to another user?
