Using classic Outlook for Windows in business environments
Thank you all for your answers.
For me the outlook message "Outlook closed while you had items open" started in June is probably the result of an update that that caused the "Start up options" submenu drop down to disappear.
Some people have updated the registry to add a new key and this looks like a temporary fix.
My view is end users should not edit the registry and that Microsoft should issue a hot fix that updates/adds the key to the registry while they diagnose the root cause of the problem.
