If you are like me using Outlook for the official stuffs and Google Calendar for scheduling personal appointments, you might want to look into SyncMyCal.

SyncMyCal makes this whole process a lot simpler by adding a toolbar into your Outlook

application that has the one click ability to synchronize your calendars. You can either choose which calendar you want to synchronize or if you want to do two way updates. A free Lite version with unlimited events with seven day date range synchronization and a Pro version for $25 with no limitations on sync dates. SyncMyCal can be used as a great tool for group collaboration too. Team calendars can be created and shared in Google, and team members can download events from a central Google Calendar version.
