Cannot open attachment in emails.

I have an msn.com email account.

I was switched to ie10 and Outlook several months ago. At first there were no problems with opening any attachments to emails sent to me.

But, a few weeks ago any attachments have an x box at the top of the attachments and I cannot open the photo or article.

For some emails if I forward the message to a Comcast email account the attachment will open, but for others it will still not open.

I have the latest version of Microsoft Silverlight and it is enabled.

This problem occurs whether I access my MSN mail through my desktop, laptop or iPad computers.

I am using Windows 7 on my desktop and laptop.

This has all become very frustrating and I'm about ready to change my main email account away from Microsoft.

I am at the point that I will never purchase a Microsoft product again.
