InfoPath Dev

I have a question. I designed the form in Infopath 2010 together with its workflow. However it turned out that the buttons (approve\reject) are not visible in email preview. It is critical for me as the approvers usually use their Blackberries and can not open an attachments. They can only preview the form in the email and have to get an option of approving it from there.

Can anyone please help me? Is is possible to have active buttons in preview?

Many thanks!

I'm pretty sure that button actions can only happen in either the InfoPath Filler or in the browser (if it is a browser enabled form). I don't believe that buttons can be clicked when the form is attached to an email view and sent via email. Sorry! Are you using SharePoint and would you consider switching to browser forms?
