Hope someone can help with this...I have a MacBook Pro with Office for Mac, and all of a sudden, when I e-mail a Word doc to a windows user, they can't open the attachment. Tried sending it as a PDF, same result. I'm sending through AOL...so I don't know if the problem is with AOL or my Mac...I've sent the attachments to two different recipients with Windows, results are the same, neither can open the attachments. If anyone is familiar with this problem, I'd love to hear how you solved it. Thanks!
