Below is a log entry for one of the missing emails which shows it was delivered to the mailbox, but going into the mail box and also into the directory structure you will find no email at all. I have gone through all the logs i can find for this one date/time and found not a single error which is extremely puzzling.
On Friday I deleted the user account and recreated the account while preserving the old email directory to see if the issue might be resolved that way.
