You would need to send the body as HTML and you can do this using html tags however you need to use the .htmlbody parameter and not .body. If you attach a word document with the signature exactly how you want I will write some html code to add for the signature. If you know html then have a look at http://www.excelforum.com/excel-prog...mail-body.html
If it is easier just attach a word document with the signature layout and I will write the html to add to the macro
