Customer had this issue this morning. They were running EMET 5.2.

I upgraded EMET to 5.5, and restarted the machine. Didn’t fix the issue.

I updated the Symantic End Point software and ran a scan. While scanning another co-worker suggested opening Outlook in safe mode. Holding the control button and double-clicking the toolbar icon for Outlook the program opened without the EMET warning.

We disabled a couple of Add-ins in Outlook. Restarted the program several times and EMET never popped up again.

I hope this helps someone else out there….
