If you create a new profile a error message with the message “Configuring Outlook” pops up and another seconed window asks to confirm the name and initials. Those windows immediately close and Outlook goes on to connect to the server and download messages. If you now try to close Outlook it won’t close. Instead you have to kill the outlook process. Outlook Safe Mode, Windows safe mode, deleting and recreating the Outlook profile doesn’t fix the problem. Each time you start outlook, it will ask for the Name & Initials and can’t be closed.
Start Outlook either with parameter /cleanprofile or /firstrun
