It may not be the most elegant way, but it certainly is a way that lets me do everything I need. I like to keep Outlook, Google Calendar, and my phone in sync with one another.
To do this I use Google Calendar Sync (

This allows me to keep Google Calendar and Outlook sync.. then I use the typical ActiveSync to keep my phone updated with Outlook. Yes its a roundabout way of doing things... but since most things are updated on Outlook, it's not as difficult as it sounds. Updating things on the phone or Google Calendar adds an extra step... but it's a free and relatively consistent method of doing this.
