Outlook / Google Calendar synchronization
I’ve been using Google Calendar Sync for several weeks now and it has removed the headaches of having calendars in two places.
Google Calendar Sync can be configured to do a 2-way synchronization, or a 1-way synchronization (in either direction). It is very quick to setup, and has very few options that need configuring.
The only improvement I would like is support for multiple calendars. I would like 2-way synchronization for my work calendar, and 1-way synchronization from my other Google Calendars to my Outlook Calendar.
