Setting up access to send email

[Mac]

I have a button on a form to run a macro set up to send an email. the macro
(SendObject) is as follows...

To: =[Forms]![Form Name]!
Subject: Your Stuff is Here!
Template File: (assusming this means an email template?) C:\path\filename.oft

When i run the macro i get a "Choose Profile" popup, asking me to choose my
email profile? I'm not sure how to set this up. I use an exchange server.
So, I choose "Exchange" and click "ok".

I then get another popup that says...
Microsoft Office Access can't send this e-mail message.
Before attempting to send an e-mail message from Microsoft Office Access,
resolve the problem identified int eh previous message, or configure your
computer to send and receive e-mail messages.

My computer IS setup.

What am I NOT doing correctly?
Thank.
