Sap shortcut Icon in outlook when double clicked asking to save!!!

Hello Experts,

I faced an issue while working with workflow, actually i wanted to make a shortcut of a transaction and send it as an attachment  in the email.From there the user will double click and will input his credentials and directly access the transaction.

Problem is the once we double click on the attachment it is asking to save first, i wanted to get rid of this.

Please suggest.

Regards,

Mahesh.
