If you are interested in Exchange Server 2007, the product team is running a series of webcasts called “24 hours of Exchange Server 2007”. As the name implies there is 24 different sessions covering all aspects of Exchange 2007. As always you can choose if you want to see them live or afterwards. The first two episodes are available on demand and the next live one, “Planning Installation” will be tomorrow. For us in Asia they are in the middle of the night so I prefer to download the webcasts and watch them when I travel.
If you are really hardcore you could wait a month or so and then watch them all in a row. Just remember to buy lots of coffee and coke to be able to stay awake J
