When using Entourage 2008 I was able to "encode" attachments for my recipient.  Most of my recipients are Windows users and I am sending them forms and documents created in Word 2011/Excel 2011/etc. for Mac.

When I sent to Windows users I was able to "tell" Entourage to encode the attachments for Windows.  If I didn't do that then my Windows-user recipients couldn't open the attachments or they opened but presented gobbledy-gook.

Now, in Outlook 2011, I can't find how to encode an email (that has attachments) for Windows users.

How would I do this?

Thank you so much!
