Cannot open Microsoft Office Documents in IE9 or IE10

I cannot open any MS Office attachments in OWA on IE9 or IE10. I can open them in firefox, chrome, IE8 or earlier. I can save them just fine and open them later, but I cannot open by selecting open. After selecting open it just opens a blank IE tab

I made sure the file association on my computer is set to MS Word (docx file)

Added the OWA website as a trusted site. Temporarily set all the permissions to low

Under Advanced > security > I unchecked "Do not save encrypted pages to disk"

Popup blocker is disabled

I reset all my IE settings and cleared out temp files, history etc.

Rebooted after setting changes in IE.
