If you combine this with the great new and free Calendar Sync tool, this is really all you need to move from Outlook to Google Apps (or, even just use both systems).
Well done, Google team! This means that the Enterprise can rely less on third party applications for basic and fundamental requirements of moving from one platform onto Google Apps. This should go a long way of increasing the comfort level for any organization wanting to make the move. Oh, and it’s all free – which doesn’t hurt either.
