Using classic Outlook for Windows in business environments
| Edited to add: Note that the registry key applies only to classic Outlook desktop software (2016, 2019, 2021, Outlook in Microsoft Office 365 software). It does not work for Windows Mail. |

Hello Dennis
You're talking about the button in my screenshot? It's not a toolbar but you can hide it using a registry key -
HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Outlook\Options\General
DWORD: HideNewOutlookToggle
Value: 1
Start typing regedit on the start menu and when the Registry Editor comes up, open it.
Browse to the path, right click on the right side and choose New > DWORD. Paste HideNewOutlookToggle, press enter then right click on it and choose modified and choose modify. change 0 to 1. \
Restart Outlook.
Edited to add: I have a ready-to-use registry key in my article at Use Classic Outlook, not New Outlook (slipstick.com)
