My dad got an important .xls file, that could possibly decide his career as an attachment that he needed to fill out and send back to the guy he got it from. Guess what. Outlook doesn't let people open .xls files, because they could potentially cause viruses.
The help suggests to upload the files to a share server.
I suggest having Bill Gates raped by OJ Simpson in his ass-hole (both of them) until a big dead duck with a clown hat comes singing 'Oh Holy Night' in the White House, or Ronald MacDonald gets 4 breast implants and stars in the next episode of Friends, whichever occurs first.
Thank you for my attention.
