Submitting HTML form data in Outlook 2010

[ramen]

Hi,

I am sending an email message that has a small html form in it (there are two
form submit buttons and an html textarea). In addition, I include a message for Outlook 2007 users:

<!--[if gte mso 12]>For the buttons to work in Outlook 2007, open the message, click the Other Actions button, then View in Browser<![endif]-->

This works fine in Outlook 2007 - when a form submit button is clicked, a new tab is opened up and the server's response to the form submission is displayed. However, when a form submit button is clicked using Outlook 2010, a new tab is opened, but there is no response - the screen is blank. The server is not contacted. Seems like a security limitation, but there are no warnings/errors that we can see. Any suggestions on how we can get this to work?

Thanks
