Have you noticed that when you receive a reply to your email that the signature you put in does not exactly look the same?  It is usually spaced incorrectly.  This is because when you send the email it is sent in Word format with an HTML format, but when you receive and email it is read in Word RTF (Rich Text Format) so the formatting does not look correct when reading.

Here's the trick to making your signature work the same in HTML messages as in plaintext and Rich Text Format (RTF) messages: Press Shift+Enter, not Enter, at the end of each line.  This option inserts a line break between the lines, and HTML messages will use a <br> tag to end one line and begin the next line immediately below, without any blank space in between. If you press Enter to end a signature line, HTML messages will use <p> and </p> paragraph tags to set off the individual lines. The default behavior in HTML is to put a blank space between paragraphs.
