Unfortunatley this did not help, and actually left Excel a little unstable but that was easily fixed with a few restarts. The only thing i could find referencing Homer Simpson was the reigstration info of Office. I checked everywhere i could to find a setting – but couldnt find one within Outlook.
It was definatley an issue caused by the Mac. The issue did not occur in Outlook for PC or using OWA / iPhone ActiveSync. Of course Mr Burns wanted this corrected. (as you can see in the example to the right, even emails received by the user showed the wrong name) When a user of a mac replied to one of there messages, the email came through showing the display name as a previous user of that mac. I had a customer email me to show me a very weird issue.
