Google Calendar Sync
Google Calendar Sync , as you can probably guess, synchronizes your Google Calendar online and your calendar in Outlook. You might want to keep your Google Calendar because of its convenient features (for instance, that it's available online, it can be shared, and has email and SMS reminders).
Plus you might also want to use Outlook's calendar because it's so accessible and integrates with Outlook's other features.
Along with your calendar data, event reminders can be synced. However, Google Calendar supports pop-up, email, and SMS reminders, while Outlook only gives you pop-up reminders. Therefore, only pop-up reminders will be synced to Outlook.
Google Calendar Sync works with Outlook 20032010.
