I always thought it would be nice to sync Outlook with the Google Calendar. I found out today that it is now possible thanks to OGG Sync.
Check it out and give it a try. There is not very much documentation, but be sure to read what documentation they do have on installing it so you can figure out how to use it after installing.
I should also mention that the freeware is limited to syncing the 3 days only – so it is not a time trial, but a free version with limitations.
