After a few days of frustration, I finally have this issue resolved.  I am so thankful that I still have some great contacts inside Microsoft that I can call on a moment's notice and they'll help me through these issues...the favors go both ways frequently, however.

First of all, I want to apologize to everyone that tried to contact me (either via the blog or email).  My email server bombed a few days ago.  It took me about 24 hrs to see the issue...I thought I simply wasn't getting much email.  Once I realized that I was only getting my POP3 email and not Exchange (IMAP) my worries began.

As those of you that know me can attest, I have a penchant for having hard drive issues (I think I live in or near a vortex of some sort).  It turned out that I had a series of CRC errors in my exchange database.  Upon performing a CHKDSK /F I realized that I had about 8 KB of bad sectors on the drive.  Once the CHKDSK finished, I moved the database, repaired it, created a new database, and restored the old data into the new one and we're back up and running great!

Thanks everyone for your patience!
