Done.  I had to disable detailed logging for MAPI.  It was filling up the HDD.  Just one day of detailed logging MAPI for 2 users generated a 39gb log file.

Perfect, Larry will be contacting you to request whatever access he needs to see / duplicate the issue.  Each and every issue we see now are unique situations that only come from unique datasets etc.  Just a small byte in the binary that is something we haven't seen before even after processing millions of messages and thousands of mailboxes with our MAPI implementation.
