Css borders in email...!driving me crazy!

I need your help kirupians…

I created an custom email personality (that’s what i call it)…which is simply a design from photoshop…brought to dreamweaver and is left a blank area to input information. that single (html) file is then put in my stationery folder in outlook. All images uploaded to the server and once i send an email i will have my design show in their email box.

I had to get that out the way so hopefully everyone is on one accord. Now the problem is whenever i add a border to any of the tables it will not showup in the email box?? i tried inline style sheet…external… @import , all with absolute urls and it still wont show?

is it impossible to do borders in email or am i still missing something? if anyone can help please do…thanks!

ps. all the images and all the other css fonts work but the borders wont…
