Outlook 2016 would not open it immediately crashes
, So...... after a bit of messing around including...
Reinstall/repair Office 2016... had to redo activation key
Uninstall latest updates today.... one for XML security!
Run in safe mode.... works ok
Reinstall todays updates again
Run Outlook as "Administrator" yep runs fine and now Outlook opens fine everytime
