Problems with email containing a .docx attachment created on a Mac

Hello Exchange Experts,

Our organization is running Exchange 2007.  We have a user that works from home and often email messages to other users inside the organization from his AOL account.  If he just types out an email message, everything works as expected.  If he sends a Word document as an attachment, he receives an NDR.  This user uses a Mac and Apple’s version of Office.  The Word documents have a .docx extension.  Word documents from all other users are working without any issues.  Below is a copy of the NDR.

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

I'm betting on it's an issue with how aol handles the attachement, see if you can't get them to send a test email from hotmail or gmail with the document and see what happens.
Alternatively you could ask him to save the files as a doc file rather than docx file through the save as menu.
