Hotmail is one of the oldest e-mail websites, and is owned and operated by Microsoft. Hotmail's features have been improved and upgraded over the years, but there are still some small capabilities that Hotmail users do not have. One of the most common complaints is the inability to permanently change the font used for new e-mail messages, which defaults to Veranda at size 10. Although there is no official method of applying another font or text size to new messages, there is workaround.
Login to your Hotmail e-mail account.
Click the "Options" link located at the top right-hand corner of the main e-mail window. From the drop-down list that appears, click the "More Options" link at the bottom.
Create a signature. Click the "Personal e-mail signature" link located beneath the "Customize your mail" heading. A new window will open displaying a blank text box.
Choose your font size and style. Using the buttons above the blank text box, select your desired font style, size and colour from the available choices.
Enter initial text. In order to retain your font options for all future e-mail messages, you must create a signature that contains several blank lines between its beginning and end. At the top of the email signature text box, enter a basic greeting such as "Dear." Skip several lines before adding your name. This will retain your font options within the blank lines, and your new signature will be displayed on all future e-mail messages.
