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.

    Perfect. I am deeply embedded in To-Dos and other classic Outlook features, so New Outlook is not of interest to me at the time being.

    Thanks!

    What I have experienced is that our users who decided to try the new Outlook, had their old Outlook profile / view corrupted so that the view was different and unusable. Their ribbon bar frequently is missing items they used heavily such as the "From" field. Yes, you can go the reset view in two places and get them back, but when you have 1200 users this creates a lot of confusion. Microsoft now stores your preferences in the cloud which means even going to the web version is not a workaround.

    "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."

    For now...

    Anyone familiar with MS knows they will kill the old Outlook far before the new one is ready for consuption and leave consumers with the choice of 1 sub-par product.

    This has been happening with the entirety of Office for 10 years now.
