Question about Outlook Express

Hello - I just switched to Outlook 2011 for MAC and I'm looking for the function I used a LOT in windows version which was the "flag for followup" there was an option in a new email to flag it and set a reminder date before sending the message.  I see the follow up flag on the main inbox view but inside a new message there is no option - am I missing it?   Seems really dumb to have to go into my sent items each time I send an email and set it to remind me!
