My Windows Live email suddenly will not attach documents in their correct format. With all types of files (Word, PDF, Excel), which I try to attach to an email, it shows up as a blank page in my "Sent Items", which I cannot open again, and the receiver of the email does not receive the attached document.

It first happened yesterday that I did not receive an attachment in a group email sent to me. When it was sent in an individual email, I did receive the attachment. Right after this, I was not able to send out my attachments in the correct format.

I can use my Hotmail address online, and attach documents correctly that way, but Windows Live is the only problem. I don't think there was any automatic update before it happened.

I have researched this problem online in the forums, and seen a reference to a Sept. 2013 Windows Update, but I don't think that is related, because my computer does updates all the time, and this has not happened before. I have seen lots of other people say they had the same problem, but nobody gave a solution in which others said that it solved the problem.

I'd appreciate some step by step instructions as to how to resolve this issue.

Thanks!
