I have a user that has been working just fine. Unless they have downloaded something, which they swear they didn't, they can open any attachment just fine and see it. All except Excel. When they right click and choose to open they get excel but the page is blank. double clicking on the document produces the same result. Powerpoint and word are just fine.
They can preview it, but that is not always the best option.
Any ideas or suggestions as to what may have been turned off in outlook to prevent excel from displaying? All versions are in Office 2007.
