TechNet Magazine - August 2007
The August issue of the TechNet Magazine is now online (it's also available as an HTML help download).
Although there's not a single article about Exchange Server, the main topic is about management. Can you imagine your Exchange servers without monitoring them? So, there are a lot of articles about System Center in general, Operations Manager 2007 and the new System Center Essentials.
BTW, did you notice that the Exchange Server 2007 Management Pack for Operations Manager 2007 is not yet available?
