I used the excellently simple SyncMyCal which allows you to synchronize your Google Calendar(s) with either Outlook or Pocket Outlook (on a PDA).
The free version allows you to synchronize appointments for a maximum of only 7 days (3 days in the past, today, and 3 days into the future). The full version (£13.50) allows you to extend your synchronization period AND setup an automatic scheduled sync (the default is every 15 minutes).
It really couldn’t be more simple. Now Jane can really keep an eye on my goings on, because if anything knows what I’m supposed to be doing it’s my Outlook calendar.
