I need to return to my classic Outlook. I need to turn off new toggle. I can't. Help
Just go to Settings ---> Apps and uninstall New Outlook. Uninstalling New Outlook will not affect anything related to your emails in Outlook, since Outlook is a just an email client.
Once you remove New Outlook, Classic Outlook will become the default version.

"New Outlook" does not appear in my apps. Only "Outlook"

Solution worked, no idea why new outlook became a default but it locked me out of accounts... keep it classic Microsoft...

I have tried this many times, whenever I turn on my system I have to do this step every time, is there any permanent solution? How can I remove this pathetic New Outlook app?

As microsoft choose to force this on paying customers and will continue to do so if you attempt to uninstall it, you have to forcibly remove the software from your endpoint.
The way to do this is as follows:
run this 'new outlook' on your computer.
go to task manager and find the 'new outlook' process running. make sure that you do not have any other outlook like classic outlook running or you may delete this instead.
right-click on the new outlook process and select "open file location".
this will open a new explorer window with the location of the new outlook application on your hard drive. save this location as a shortcut or a link so that you can get back to it in future.
the file that is the new outlook executable is called 'olk.exe'.
restart your computer in safe mode. as soon as you are in safe mode, go to the location of the file olk.exe - the location that you should have saved earlier.
delete this file.
restart your machine back into normal mode.
this deletes the 'new outlook' software and stops it from running. the icon will still be present in start menu but this cannot be accessed by microsoft for any purpose because the software has been deleted.
this also prevents them reinstalling this if you attempt to uninstall it through their operating system.
behaviour exhibited by windows and outlook after this forced removal includes an error message showing every single time that classic outlook is attemptedly opened. this comes from the vendor attempting to force the user to change to their 'new outlook', because their operating system tries to reroute any attempt to open the classic outlook executable which is titled "OUTLOOK.EXE" to this new 'software'. in this specific case the 'OK' link is selected and classic outlook opens just fine thereafter.
Obviously: it needs to be said that you take full responsibility for any modifications that you make to the software on your own computer and you attempt the process outlined above entirely at your own risk.

CMAPman870 I’m piggybacking on this old post because I’ve been having the same issue for months but I was always able to finally get to my old mail until earlier this week, no matter what I did, it would only open the new one which I absolutely hate.
After trying everything including trying (and failing) to find the toggle option and other solutions, I followed your advice and uninstalled NEW outlook, but it did remove the old one too! I tried accessing it through my search bar, windows bar.. nothing, completely gone.Any recommendations on where to find the old one again?
When I do a search to download it, it only gives me the new option. - KLCharlesMar 17, 2024Copper Contributor
UNINSTALLED New Outlook. Now Classic Outlook won't launch. I'm at my wits' end. I needed to be able to view past Calendar events and appointment as entire Calendar was blank, as was Contacts. Email ok. Where can I adjust the range of dates so I can see older info? Help!
