:16:00: What are your top tips for IT Pros who have to install Exchange Server 2007?
"....If you've got some clustering replication going on, one of your options is Standby Cluster Replication (SCR)....One thing a lot of the people don't realize is that when you are using SCR there is a log replay lag time....You also need to think about your operating system - what OS are you deploying. There are benefits and disadvantages of the OS that are supported (Windows 2003 and Windows 2008).....CCR (Cluster Continuous Replication) or SCR - which one to implement? The recommendation is to implement a combination of both....The tool you need to run just before and just after installation is the EXBPA (Exchange Best Practice Analyzer) which is a free download from the Microsoft site...."

:29:11: What are little known gems about working with Exchange Server 2007?
....Exchange User Monitor is a little tool which allows you to monitor Exchange client connections to Exchange server and is available for free on the Microsoft website. It is particularly useful when troubleshooting RPC latency issues to an Exchange server and helps you identify the source of that problem....Another useful tool is the Performance Counters from the Performance Console in Windows....Pipeline tracing (used to troubleshoot transport issues) is an advanced diagnostic command that you run through PowerShell that allows you to monitor messages as they flow through the transport filters....Use the Get-ExchangeServer PowerShell command line (when you have a distributed environment and you want to discover which domain controllers you are talking to)....Exchange Connectivity tool allows you to connect connectivity from the internet for things like Autodiscover...."

:35:49: What are your best practices for Unified Communications?

For small business I think it is going to be even more interesting...."

:58:33: What are your recommendations around Microsoft Certification Exams?
"....Exam 236 is the exam on Exchange 2007 Technology Specialist and once you pass that exam you basically demonstrate that you know how to configure and troubleshoot an Exchange server....If you work in a more Enterprise environment where you are looking at the design and planning phase of Exchange then maybe you need to look at the IT Professional certification.
