I have an Office365 exchange account with multiple aliases. When I use Office2010 or OWA and I create a new email, I just click the "From" field (assuming I've enabled it) and type any of my alias addresses to send as. It's usually just a hybrid textbox and drop down box. In Office 2011, the From field is just a full drop down box preventing me to type anything. It's forcing me to choose only between the accounts I've set up.

Is there a way to send as one of my alias addresses in Outlook 2011?
