Using Outlook 2003, I want to know if I can set up my calendar to
automatically accept meeting invites.

From a search in Help on 'auto accept meeting invite':

On the Tools menu, click Options, and then click Calendar Options.
Under Advanced options, click Resource Scheduling.
Select the Automatically accept meeting requests and process cancellations
check box.
You can then select the following options:
Automatically decline conflicting meeting requests
Automatically decline recurring meeting requests
