Lost emails after Office Update 14.3.1

I am running Mountain Lion and was prompted to download the Office 14.3.1 update. I downloaded/installed it successfully, and when I opened Outlook after the update I discovered that all emails in my Inbox and Folders that were sent or received in the past six days are absent. I searched everywhere including the deleted folder and could not find a trace of the emails. I rebuilt the database and that did not bring back the emails. Any suggestions?
