Extensive in-depth experience with NT and MS Exchange dating back to 3.1 for NT (no, that's not a typo) and 4.0 beta for Exchange. Several certs and alphabet soup after my name. I spent eight years at Microsoft, from '93 to 01, supporting first MSMail than got on Exchange pre-4.0. I've been doing Exhange ever since. I currently own a consultancy in the DFW area. I am also a Microsoft MVP and have been involved with that program since '94.
