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.

    If you go to your start menu, you should see two versions of Outlook. I have two. One is the old version and the other one is the new one. Hopefully this helps you get back to the old one. There are alot of missing features in the new version that is needed for my job.

    Thank you!! This was the only solution that was helpful. For me the toggle only appears in classic outlook. It's not in new outlook. Seems like microsoft should put the toggle in the new outlook too so users can switch back and forth if needed.

    All you have to do is uninstall new Outlook if you don't want both.
