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.

    I turned off the New Look toggle on the top right and the UI switched back to the classic within seconds.

    Good luck

    Good point about shared calendars, however, my main issue is external clients scheduling me. If I cant edit my events then I cant use the new UI. Plain and simple.

    Thanks again for the internal solution

    I switched to the New Look and then switched back within minutes. I can no longer EDIT a meeting that I did not create. The edit option is gone, I checked settings and was not successful in figuring it out, so I switched back to the classic look. That's too bad because some of the new features would have been good to try.

    That does seem to be the case for an individual event that someone invited you to (probably just something they haven't gotten to yet, since as you pointed out old Outlook can).

    However, if you're talking about shared calendars, then you'll see this in Settings, Calendars, Shared calendars: https://i.imgur.com/Oy55AcG.png

    If that's on "Can edit" then even new Outlook can.
