Hi Weelass1968 ,
Thanks for visiting our forum.
Does the people pane you mentioned here mean like below?

If so, according to my tests,
the option of the people pane is related to the Outlook Social Connector add-in in Outlook. If you disable this add-in, the people pane will disappear and you will also not be able to find it in the customized ribbon in Tabs and All commands.
To conduct further researches on your issue, please follow the steps below and see if there is any difference:
- Make sure you have enabled the Outlook Social Connector add-in first
- And then, reset all the customizations via Options > Customize Ribbon > Reset
- Restart your Outlook
Besides, as I know, the Ribbon and QAT settings are stored in office UI-files: C:\Users\username\AppData\Local\Microsoft\Office.
To get people pane back, you may also try to rename the office UI-files and restart your Outlook to see if it works.
If the issue continues, please try
repairing your Office installation.
If this is not your case, please provide me with more information related to your issue.
Hope this can be helpful.
Regards,
Jeff Yang
