Company wide standard signatures
 

I am trying to push out standard outlook signatures and I'm having
trouble with formatting. The signatures work fine upon sending, but
replying they seem to be changing fonts from PC to PC. My main concern
would be to lock down the signature block "in-house" first, then move
on keeping it's format when sending to and receving from outside
sources. We are using basic fonts, and no obscure images or anything.
Does anyone have any ideas with major scripting or hacking what places
i can look to ensure my signature block stays as we want it?

Thanks
