Webcasts de suporte da Microsoft

A Microsoft disponibiliza através do seu serviço de webcasts, apresentações técnicas sobre os seus produtos.
Para Janeiro e Fevereiro estão agendadas algumas relacionadas com messaging que me parecem bastante interesantes:

• TechNet Support WebCast: Secure messaging in Microsoft Outlook
  Thursday, January 27, 2005: 10:00 A.M. Pacific time (Greenwich mean time - 8 hours). Presents techniques to identify and troubleshoot typical S/MIME issues that may occur in Microsoft Outlook. Discusses encryption, trust, configuration, and use of Outlook with and without a Microsoft Exchange Server in the environment.
• TechNet Support WebCast: Performance baselines and troubleshooting analysis in Microsoft Exchange Server 2003
  Wednesday, February 23, 2005: 10:00 A.M. Pacific time (Greenwich mean time - 8 hours). Explains why baselines are important and describes data analysis for problem identification. Discusses the Performance Monitoring tool, counters required for baselines, and counters and data analysis for troubleshooting performance-related issues.
