TechNet Magazine - June 2007
The June 2007 edition of the TechNet Magazine is now available online.
This time the main subject is security, so expect some good articles, signed by some of the most renowned authors, such as Steve Riley or Mark Russinovich. So far I haven't discovered an article covering Exchange or messaging besides Windows PowerShell, which is somehow related with Exchange Server 2007 management.
The magazine is also available to download as a standalone HTML Help file (.chm).
