How To Open Outlook Task window from client side with javascript

Not for IE users.

I want to Open the task window of outlook when the user click a button in my web page.

i mean without using the ActiveXObject("Outlook.Application");

and again, method that will work for all browsers especially FF or Chrome.

and i need it to be from the client side, not s开发者_运维知识库erver side.

BTY: i assume the user is using office 2007

thanks

Standards-supporting browsers don't support this proprietary behaviour, which opens up security holes anyway.
