I usually underline for emphasis, but some applications do not
recognize underlining. Then I use uppercase for emphasis. But
sometimes, I do not decide upon emphasis until AFTER I wrote the
message. That is why I need to change case after I wrote an e-mail
message in Outlook.
If you use Word as your mail editor, select the text, click Format>Font.
Check "All Caps". If using the Outlook editor, you're out of luck. It
doesn't have the ability. If you've an all caps font installed, you could
change the selection to that font, but that's about it.
