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?

    This worked for me. I did it with sudo in front of it also.

    Open Terminal, enter the following:

    defaults write com.microsoft.Outlook EnableNewOutlook -int 0

    Hit enter.

    It's the full line. But hopefully, after having done that once, it isn't needed anymore.

    Many thanks for the suggestion, belatedly. I'm a bit dumb about this so am not sure which part of the code to type into Terminal. Do you type in all of this:

    defaults write com.microsoft.Outlook EnableNewOutlook -int 0

    or only part of it?

    I tried something which seems to have removed the banner appearing but don't know whether it was just a coincidence and would like to be ready in case it happens again! Thank you.

    I cannot agree more. This has been an awful experience with the constant forcing only to make me repeal the change. Too much just doesn't work. I hope Microsoft learns from this.

    Thank you! The toggle switch disappeared and I truly hope the automatic switch to New Outlook will not appear any longer.
