I´m trying to create an html email signature for Outlook 2007 and 2010. And for those who will get such mails on an IOS devices, like an iPhone, I would like to keep the correct font size. Therefore I´m using "-webkit-text-size-adjust:none;" (or 100%) in my code. But unfortunately Outlook extracts the -webkit information, equal to where I put it: internally (with tag) or inline (directly within the used tags).

I even made the signature through Outlook 2010 and afterwards edited the htm file in the %AppData%/Roaming/Microsoft/Signatures folder. Just because Outlook interprets the code the wrong way. So I insert it again correctly. The code gets better. But it still extracts the -webkit css code.

I also made a new stationery in Outlook 2010 and edited again the htm file within the %AppData%/Roaming/Microsoft/Stationery folder. But no change.

I also tried to use conditional css:

<!--[if !mso]><!-->
<style type="text/css">

Nothing works. Can anyone help me?
