Using classic Outlook for Windows in business environments
Ignore the nonsense.
If the people module in classic Outlook is not loading, restart Outlook - if it is still a problem, start with repairing office.
Also - after you close outlook to restart it, look in the notification tray area on the right end of the task bar - is Outlook still showing, possibly in a gray color? Check in task manager and if it is there, select it and End task. Then restart outlook.
