Move navigation bar from side to bottom in Outlook using Registry fix
1. Enable Outlook, you can see the navigation bar is now located in the upper left side.

2. Hold down the Windows key and R key on your keyboard to open the Run dialog box. Input regedit in the Open box. Then click OK.

3. Then a User Account Control dialog box pops up. Click the Yes button to continue.

4. In the Registry Editor window, navigate to the following path: HKEY_CURRENT_USER\SOFTWARE\Microsoft\Office\16.0\Common\ExperimentEcs\Overrides

5. Locate and click the “Microsoft.Office.Outlook.Hub.HubBar” string value in the Name column in the right section of the page. Then set the Value data to false.

But in my case, the “Microsoft.Office.Outlook.Hub.HubBar” string value in this registry key doesn’t exist. So I should create a new string value named “Microsoft.Office.Outlook.Hub.HubBar” in this location first.

6. To create the “Microsoft.Office.Outlook.Hub.HubBar” string value, please right-click on the Overrides folder, then click New > String Value in the popped-up menu lists.

7. Copy and Paste “Microsoft.Office.Outlook.Hub.HubBar” in the text box.
Tip: If the name of the string value is not in editable mode, please right click it and select Rename from the context menu.


8. Double-click on the newly created string value. The Edit String dialog pops up. Type “false” in the Value data box. Then click OK.

Now restart Outlook. You will see the Navigation bar is back at the bottom of the Outlook page like it used to be.

Note: If you want to restore the left-side navigation bar setting, just locate the “Microsoft.Office.Outlook.Hub.HubBar” string value in the Registry Editor window, right-click on it, and click Delete.
