Want to use email alias (forwarded) as the reply email instead of the default email Using Outlook 2007 with Google apps

Question

I have one main email address using Google apps and 3 alias email addresses within the same domain (I believe Google calls these accounts group accounts).  I would like my replies to appear to come from the alias whenever an email is received through
it.  Is there a setting to do this automatically. Currently I use 3 separate accounts on Outlook where everything is filled as if the alias account is a real account except for the username and password - where I fill it out with my real email login info. 
I then had to disable these 3 accounts from the RECEIVE group (under send/receive) and make sure I use the "account" drop down when I'm replying and pick the correct the email alias.  The problem is that I usually forget to pick one or pick
the wrong one.  If there a setting that would do this automatically it would be a life saver and probably a job saver too :-).  I would even take an Outlook Addin...if there is such a thing.

Diane:
This worked perfectly for me, I tend to read most of my mail on the default reading pane (as opposed to opening the email completely -which doesn't work).  I Actually created three different Macros for REPLY, REPLY ALL, and FORWARD and replaced the
buttons on the ribbon so I wouldn't click them by mistake.  The only change (besides the obvious changes) I added a line "strRecip = LCase(strRecip)" because I noticed the Macro would not work correctly if the person used uppercase when typing the email
address...for example if they typed it as [email protected] it would work fine but if they typed it as [email protected] or [email protected]  or even the domain itself it would NOT work.  With this addition everything works! I'll post this on the
bottom of the macro link too...I would have typed it there directly but you probably don't visit that page very often and I wanted to make sure you got my response.
