Blogs can be a fabulous resource for information from some of the best Exchange admins and experts on the face of the planet. A few worthy of your attention...
1. You had me at EHLO. This blog is maintained by the Microsoft Exchange Team. In their "about" link, they write "
This is an official blog of the Microsoft Exchange Team - a group that plans, discusses, designs, changes, programs, tests, deploys, documents, supports and fixes the Microsoft Exchange Server product - the best messaging and collaboration server around! :) ".
It's a rock solid source of information from the people that create the product.
2. My good friend Jim McBee's blog. Jim is the author of some of the most important technical title's relating to Exchange. When I have a question about Exchange and need to be reminded that the weather is better in Honolulu, I ping Jim on Windows Live Messenger if he's available.
3. Another friend is Bharat Suneja. He maintains the Exchangepedia blog. This blog in itself is a tremendous undertaking, and there is little doubt that Bharat is one of tghe hardest working trainers and consultants in the Exchange theater.
4. David Elfassy and I go back a few years as well, and I'll be working with David at theis year's Microsoft TechEd, the annual technical education conference. David prepare's some of Microsoft's best Exchange courses, the one's so jam packed with information they're difficult to finish in the time alloted. His blog on MSN Spaces can be found here.
5. There are two people I talk with when it comes to the topic of clustering Exchange, Dr. Russ Kaufmann & Rod"*Mart"Fournier. Rod, if you read this, we need to figure out when we can go fishing... the Lake of the Ozarks or Tablerock, your call.
There are plenty of other very informative blogs out there regarding Exchange 2007 and its features. I want to thank all of those that devote so much of their personal time to maintaining these very informative sites... it allows me to say "check this out over here" and be lazy.
