'Close Outlook, and then in the registry editor, navigate to the following registry key…
To open the reg editor:
In the search box on the taskbar, type regedit, then select Registry Editor (Desktop app) from the results.
HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Common\ExperimentEcs\Overrides
Locate the “Microsoft.Office.Outlook.Hub.HubBar” string value and set it to “false“. If there isn’t a “Microsoft.Office.Outlook.Hub.HubBar” string value in this registry key, create a new string value in this location called “Microsoft.Office.Outlook.Hub.HubBar” and set it to “false“.
You can now open Outlook again and you should be able to enjoy your Navigation buttons back at the bottom of the screen again'
