Message center

This is, sadly, more important than you might realize. Microsoft has, in recent years, been very assertive about shutting down software products, applications, and options that some businesses have come to rely on. The Message center is where announcements of new products and downgrades or retirements of older products will appear, and if you don't stay abreast of what Microsoft is doing, you might find yourself blindsided. The Message center is also accessible under Health | Message center in the side navigation pane.
