How to permanently prevent Outlook for Mac from switching to the new GUI?

Outlook for Mac is periodically insisting on changing to the new Outlook for Mac experience. I do not want this. Period.

I have tried the New Outlook and reverted back to the current and much-preferred version, since the New Outlook does not suit my needs. Moreover, after an automatic restart into the New Outlook and having to revert, it is not returning to the state it was in. I do not want to use the New Outlook and I certainly don't want to fix all issues after reverting.

How can I permanently prevent Outlook for Mac from forcing me to use (and revert from) the New Outlook?

Can I set a preference so that it will not ambush me again in the future?

    Have you tried this command to stop it trying to switch you to new version again.
    You have to run it from a terminal session (can't remember where I found it)

    It does seem to stop the prompt / warning that next time you start it will the 'new outlook'

    defaults write com.microsoft.Outlook EnableNewOutlook -int 0

    Yes, they've not only done it to us, either. At work I have to use MS Windows laptop with MS Office and they've just repositioned all the buttons (for calendar, favourites, tasks, etc) to the top left side. No choice to switch back. Just because MS think it's an improvement didn't mean the whole world should have to go along with it. We should have s choice

    Applicable to Outlook Windows only and off-topic for the Outlook Mac discussion, but we just went through this at work also. You can move the buttons from the sidebar back to below the folder list.

    Go to Options, Advanced, and un-tick the box which says 'show apps in Outlook.' Restart Outlook when prompted and you should see the sidebar disappear and the navigation buttons will return to the bottom of the panel.

    Aren't you worried that it will, and then you won't have the toggle switch to change back?

    If you want to re-enable the toggle, paste the same command into Terminal but change the last character from 0 to 1.

    defaults write com.microsoft.Outlook EnableNewOutlook -int 1
