I am having some wierd issues on one of the email accounts for a customer I manage. Recently his exchange account when accessed in outlook 2003 will start deleting all email messages in the inbox. I had to create another folder and have all message routed to that on to save all of his incoming emails. I have already scanned for viruses using AVG. None were found. I have disabled all redirect rules except for the ont to save the emails. Whats most wierd is that it will only delete email while being accessed by Outlook on any computer. If accessed through web app or by phone will not remove any emails. So i believe it has something to do with settings that the user changed under thier outlook account.
This user does tend to play with alot of settings, so i was wondering if anyone knows of settings in outlook that could cause such behavior. I myself do not really use outlook that much, tend to use phone or web app as those are always readily available for me so i am having to do alot of searching through settings and i have yet been unable to find documentation on outlook. Any help would be much appreciated.
