I have been with Microsoft PSS on the Exchange Server support team for about 4 years. During this time, I have been a support engineer, a beta support engineer for Exchange 2000 SP3, and a Technical Lead.
My principle areas of Exchange expertise are the Admin interface, Setup/Deployment, Information Store, and Clustering/Reliability. Exchange Clustering is a particular interest of mine and I have written, cowritten, or technically reviewed several whitepapers and numerous KB articles on this subject. I've also presented several Technet webcasts and am a frequent contributor to the Microsoft.Public.* Newsgroups.
I am currently dedicated to the Exchange 2003 SP1 release, supporting problem investigation and escalations for our Technology Adoption Program customers as they validate the product.
