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?

    Same question here...

    The banner atop my outlook says that the next time Outlook restarts it will launch the new outlook and like you all, I already battled with the mess of new outlook.

    The "Contact Support" answer to my question of how to opt out of the new outlook said:

    Currently the option to disable the prompt window is not available. We have notified the engineering team about this, and the concerned team is working on it. Since this needs to be tested and the fix needs to be rolled out, we would not be able to provide an ETA on the same.

    However, if you do not wish to see the prompt anymore, kindly follow the below instructions - 1. Open Terminal (this can be searched from Spotlight located at the top right)2. Type in the commands as under -defaults write com.microsoft.Outlook EnableNewOutlook -int 03. After which, hit enter in TerminalThis should disable New Outlook and the prompts for it.

    In response to my question if the terminal command will prevent the switch or just remove the announcement, the answer was:

    Yes, the prompt to switch to New Outlook will not appear anymore and it will not switch to New Outlook interface automatically.

    Thanks for that!

    One step in the right direction.

    Now hopefully this also means that if there’s an updated version somewhere down the line, it will be similar or better than we have today with our tried and trusted old/legacy/current/normal version.

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

    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.

    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.
