Ryan Gregg, Program Manager for Microsoft Outlook, has announced on his blog two new Outlook Gadgets for Windows Sidebar, both of which bring Outlook to your desktop for easy, real-time access. Go here to download the Outlook Upcoming Appointments Gadget, and here for the Outlook Tasks Gadget.
These two gadgets are a great example of Windows Vista and 2007 Office System working in tandem -- both patch into your Outlook 2007 settings to use the same display theme you're currently using in Outlook, and also allow you to open the respective task or appointment simply by double-clicking it in the gadget.
