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.

    Hi rseiler

    Tried this but the registry entry was already set to 0.

    Kept struggling to find an answer but then today my outlook wouldn't work at all.

    Tried a couple of solutions sugested by mocroft (in the head) which were typically useless but stumbled across a way to uninstall the app and settings.

    Then I clicked on the Outlook App link again and voila opened straight away and into the old version. No problems so far. I'm going nowhere near the "Try the new Outlook button again but if MS roll this piece of **** out I'm moving to another email provider.

    My solution might not work for everyone but it's so simple that I don't know why ms didn't post it. Or maybe I do !!!

    Anyway if anyone is still having issues going back to the old version you can message me and I'll try and put up details of how I did it.

    Just do a search in the Windows taskbar for Outlook. The old app should be there.

    I had pinned the new one on my Taskbar. When I unpinned it the old one was available again from the Windows key. I had to start in Safe mode, close it and restart my PC, but thereafter I was back with the old one OK
