The default font on my live mail has suddenly changed to 8point characters even though the font is displayed as 12 point.  The only way I can get the desired 12 point is to create my own Stationery option.  This is cumbersome and I would like to know how to restore to a 12 point default.

 How can I restore the normal type size to my emails? Everything else is still in the usual normal type size, but emails are so small (about six point) that I can hardly read them..

I have been trying to get my hotmail. I keep getting the error message 800488fe, and it asks me for personal information like secure words and credit card information. Is this legitimate or someone phishing. How do I get my account back. I created a new account to get to this point. Thanks.
