This is for anyone else who no longer sees the button to switch back to the old outlook. I have included step by step photos to get back to the old outlook!

First click \"Help\" at the top left.

Below \"Help\" should bring up another menu, now select \"Feedback\".

Now look to the very right and you should see the option to select a feedback option,

select \"Report a problem\".

Now you should see a box where you can type what the problem is, make sure to clearly mention that you cannot switch back to the old outlook, the button is missing and you want to switch back to the old outlook, this is important because when you submit this answer it will scan your message and generate possible solutions.

Once you've filled out the box with your problem, scroll down, click yes or no on both options (it doesn't matter what you choose but you need to select an answer for both), then click \"Submit\" at the bottom.

It will diagnose the problem and match you up with one or more possible solutions, make sure you see this one below that says \"toggling out of the new outlook for windows preview\", DO NOT CLICK \"Yes\" AT THE BOTTOM or it will end the feedback and assume you got your answer and you will need to restart this process. Instead you need to click on the arrow that is circled in this picture.

Freedom awaits, now click on \"Do it for me\" and it will automatically take you back to the old outlook. Congratulations! You've graduated from this circus of chaos and confusion. Farewell, and may your future endeavors be as comforting and delightful as a slice of warm, homemade buttered bread.

after submitting and waiting for diagnosing process, no other selection for Possible solution. only confirm \"Feedback to Microsoft\" text. moreover when I start Outlook app (aka old version), Outlook app display a box ask to open in Safemode....then....nothing happen. really frustrated with new outlook :(

troyb16 Solution didn't work for me, looks like I'm stuck with the waste of space new outlook

troyb16 Thanks. I did that before. Didn't work.

I'm using now THUNDERBIRD. It's a Mozilla Mail reader and is OKAY, not like the great classic Mail App, but it's straightforward, at least...

troyb16 I found an alternative solution. In New Outlook
1. Click the \"Help\" menu
2. At the right end of the \"Help\" menu, select \"Go to Classic Outlook\"
Once I did that, the Windows \"Mail\" app icon would once again launch Windows Mail rather than launching New Outlook.

i think the removed that option doesnt go back anymore .. i am missing all my appointments today and upcoming weeks birthdays todos and what else was in my agenda its all gone because i cant switch back. i have been trying to search for the pst file i gues i must wait from my clients to call me where i am at..this sucks big time.. iam loosing money and dissapoiting people upcoming weeks i wonder if i can hold microsoft responsible  troyb16 

nope it is all gone 😞 troyb16 

I followed the steps, asked the system to switch me back to old outlook and then was asked for my email and password.  The response was

\"We couldn't log on to the incoming (IMAP) server.  Please check your email address and password and try again.\"

I have tried this with both of my email accounts with the same results. 

Did you ever get yours working with Classic Outlook? I'm having same issue. \"New\" Outlook works fine, but when attempting to switch to \"Classic\" it gives me IMAP issue you stated above even with the same exact info I've entered to set up the \"New\".

The smart junk email folder is what is driving me insane, just because I delete an email a couple times doesn't mean I never want to see it again yet I don't want to turn it off completely. And the fact that I can't use a .pst where I like to offload the hundreds of emails my wife gets from stores and such. I absolutely detest having hundreds or thousands of emails in a single inbox and even worse that not having a .pst now means I can't access my old emails that need to be saved.

For Mail and Calendar users, you are less than six months away before New Outlook will be \"The Outlook.\" Reverting to the classic Outlook is not recommended despite the missing features.

I have a video playlist to assist end users with their New Outlook journey. It includes monthly feature rollouts, workaround solutions, and a discussion of limitations.

Hi Teresa_Cyrus 

I understand your enthusiasm for the new Outlook, but it's important to note that the new Outlook is essentially an encapsulated version of the Outlook Web App (OWA), functioning more like a browser within an EXE that displays an internet site. This makes it fundamentally different from the classic Outlook application.

The classic Outlook is maintained until at least 2029 for a reason. It offers robust, offline functionality and a feature set that many users rely on for their daily operations. While the new Outlook has its merits, it's not a direct replacement and lacks some of the depth and capabilities of the classic version.

For those reasons, many users might find the transition challenging. It’s crucial for Microsoft to develop a truly new version of the classic application that incorporates the strengths of both platforms, rather than just repackaging the web app.

I appreciate the resources you've provided for the transition, and I'm sure they will be helpful for some users, but in my opinion it's not a good answer to the question asked.

Worked, until I closed and opened again!

Only a registry entry should fix this maggot mass.
