I worked for Microsoft as a messaging consultant for 13.5 years, but wanted to get off the road, so I could be with my kids while they were in high school. I left for 6.5 years, working for two large Midwestern corporations, supporting Exchange. Once my children graduated, I came back to Microsoft, and have taken a position as an Exchange PFE, supporting the public sector. About my responses here: I normally look for the items that have no responses (hence, the ones no one knows the answer for right off). It's worked out pretty well, so far, and I believe I've helped quite a few people with their issues.
If you have questions about PowerShell with Exchange, I consider myself very proficient, so feel free to post your questions and I'll see if I can get you an answer.
