When I want so send a new e-mail, where do I find the option to choose which alias from to send it? Is there a drop-down box with all aliases or something anywhere in the "mew message" page that I deliberately searched for, yet missed? Of course I am not interested in the "work-around" solution, like changing primary aliases every time before sending a new message...
I'm completely new to Microsoft webmail, so be patient with me. :)

Thank you.
