Switch from 'new' Outlook (2023) to 'classic' outlook

I need to go back to the Classic version because the 'new' Outlook lacks some features that I need for work.

This webpage https://support.microsoft.com/en-us/office/getting-started-with-the-new-outlook-for-windows-656bb8d9-5a60-49b2-a98b-ba7822bc7627 states "You can switch back whenever you want, just switch the toggle off in the new Outlook and it will automatically open the classic version."

There is no toggle. Is there any other way I can undo this update and go back to the previous version?

EDIT: Moved FROM Microsoft 365 Insider / Outlook / Windows TO Outlook / Outlook for Windows / For business.

Outlook | Windows | Classic Outlook for Windows | For home

Once flipped on, the toggle is irrelevant since the "old" version still exists. Just run it. You should still be able to find its shortcut in Start (and wherever else you might have had it before), but if not you will see outlook.exe in one of these places (may vary slightly depending on edition), so if necessary make a new shortcut:

C:\Program Files\Microsoft Office\root\Office16

or here:

C:\Program Files (x86)\Microsoft Office\root\Office16

The nice thing about the New Outlook is that it's not an either/or proposition (like New Teams is). You have both old and new. You can even run them concurrently.

But if running that actually runs New Outlook for you (some have reported that's the case), then either:

  1. Uninstall Outlook

or

  1. run Regedit.exe and go here (or the same with 15.0, if you don't have 16.0):

HKEY_CURRENT_USER\SOFTWARE\Microsoft\Office\16.0\Outlook\Preferences

And in that you will see UseNewOutlook

Set it to 0, which means that running old Outlook actually runs it.

    Yes, however

    When going back to the old outlook everything is OK, however when I open an e-mail in old outlook and press an e-mail link it will start opening the "new outlook", taking a lot of time and forcing me to use the new outlook

    How do I remove the "new outlook" completely?

    "New outlook" does not exist at that position at all. There is place to put a "0"

    I even spent an hour and a 1/2 with the Geek Squad who was not able to get my old outlook running again.

    Microsoft has essentially damaged my ability to operate my own system. I did not ask for new outlook.

    There is no toggle switch.

    Hello Rseiler: I don't see UseNewOutlook under HKEY_CURRENT_USER\SOFTWARE\Microsoft\Office\16.0\Outlook\Preferences. Any other way I can try?

    Thank you!

    No "toggle switch" appears. When I entered "registry editor" to "unhide" the switch, it was not there as was shown in the examples on the internet.
