I forgot to mention!
Recently I started recording a TechNet Tip of the week segment which will get attached to the TechNet Radio interviews that are posted to the TechNet Radio site (http://technet.microsoft.com/en-us/bb510143.aspx). The two most recent segments deal with troubleshooint email connectivity with Outlook, as well as using the Exchange 2007 Toolbox utilities.
Also, sorry about the full URL links on the last two posts. I am on a backup machine that I have not loaded Live Writer to yet so I using the default editor.
