Synchronising your calendars

A familiar story: you prefer Thunderbird but most of the G-men use Outlook and keep sending you meeting invites that come out as gibberish. You'd also like to be able to update your personal or work calendar whilst not on location. This stay in synch with GCal and Thunderbird article promises to do all that for you.

I've taken all the necessary steps; now I need to get into the office and send myself a meeting invite from Outlook and see if the wording on the tin is correct..
