Hey All, Uninstalling Outlook from my new PC and reinstalling it from this link worked but I feel the need to provide all the options that I tried just in case my solution does not work for someone.

I also like my icons to be on the bottom and not the left sidebar (by default) so I went to File>Options>Advanced>uncheck Show Apps in Outlook . I also right mouse click the Ribbon to Show Classic Ribbon. I hope Microsoft stops with all these changes. They are a time suck to fix! Try these solutions!

Here’s how you can permanently disable the new Outlook and revert to the old version: Step 1: Disable the New Outlook Toggle Open Outlook on your new computer. Look for the "New Outlook" toggle in the upper-right corner. Turn the toggle off to switch back to the classic Outlook. Restart Outlook and check if it stays in the old version. Step 2: Prevent Automatic Reversion to New Outlook If it keeps switching back: Go to Windows Settings: Press Win + I to open Settings . Navigate to Apps > Installed Apps (or Apps & Features). Look for "New Outlook" in the list. Uninstall it (this will prevent Outlook from reverting). Modify Outlook Settings in Registry (Advanced Fix) If it still reverts, you can block the new Outlook via the Registry : Press Win + R , type regedit , and hit Enter .

Now, about that horrible Copilot. :(

Hi Kerry, Thank you for your response. I have submitted my feedback multiple times to Microsoft, but based on these recent UI/UX changes, it seems clear that user opinions were not a priority in the decision-making process—unless, of course, focus groups were conducted, which I highly doubt. As a developer myself, I understand the intent behind improving the user experience, but in this case, the changes have done the opposite. No one was asking for these updates, and judging by the discussions in these forums, many users are frustrated and spending unnecessary time trying to fix what wasn’t broken in the first place. That said, I do appreciate your response and hope that my feedback helps prevent others from losing valuable time adjusting to changes they didn’t ask for. M.

I really don't like the new version of outlook. Please can you get ALL the removed functionality back Please also make it so copilot doesn't keep appearing at the beginning of where I'm working - if I want to use copilot I'll look for it.

YES! That's what is so wonderful. Everything we love about the old outlook will come back. You'll be so happy, you'll cry. I was so relieved when this fixed my issue.

@Mallory D, did reverting to Outlook classic version fix all the dysfunctional elements of the new Outlook that create problems for workflow? Things like being unable to click on a PDF email attachment and have it open, without downloading it first? Or does it just 'look' like the classic version in terms of ribbons? Trying to decide if its worth taking the plunge and reverting. Thanks,

Dear Mallory D Good day! Thanks for posting in the Microsoft Community. We'll be happy to help! First of all, we regret for the inconvenience caused to your work. Based on your description, at first let me say a huge thank you for taking your time to do a lot of testing and sharing everything here, I read everything you wrote with all the seriousness and I believe that users who are experiencing similar problems will benefit a lot if they can see what you have to offer! In the meantime, I highly recommend that you copy your ideas as well and submit them to Outlook for feedback, if it's convenient. Because the default feature changes of the product are decided by the development team and the design team of the product. And about your suggestions, I also believe that this is the voice of many users, everyone is anxiously looking forward to early improvement, in order not to waste more time and better help you, I strongly recommend that you submit your valuable suggestions to outlook feedback so that relevant technical developers and designers can see your valuable suggestions. Please believe that the relevant departments of Microsoft will strive to improve themselves after seeing your valuable suggestions, and your valuable opinions will also help more users and make the work more efficient. Thank you in advance for your contribution!

Hey All,

Try these solutions!

To use the classic version of Outlook, but it keeps switching back to the new Outlook. Here’s how you can permanently disable the new Outlook and revert to the old version:

Step 1: Disable the New Outlook Toggle

Open Outlook on your new computer.
Look for the "New Outlook" toggle in the upper-right corner.
Turn the toggle off to switch back to the classic Outlook.
Restart Outlook and check if it stays in the old version.

Step 2: Prevent Automatic Reversion to New Outlook

If it keeps switching back:

Go to Windows Settings:
- Press Win + I to open Settings.
- Navigate to Apps > Installed Apps (or Apps & Features).
- Look for "New Outlook" in the list.
- Uninstall it (this will prevent Outlook from reverting).
Modify Outlook Settings in Registry (Advanced Fix) If it still reverts, you can block the new Outlook via the Registry:
Press Win + R, type regedit, and hit Enter.
Navigate to:

CopyEdit

HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Outlook\Preferences

Right-click and select New > DWORD (32-bit) Value.
Name it: DisableNewOutlookToggle
Set its value to 1.
Close Registry Editor and restart Outlook.

Step 3: Repair Outlook (If Needed)

If Outlook still keeps switching:

Go to Control Panel > Programs > Programs and Features.
Find Microsoft Office in the list.
Click Change and select Quick Repair (or Online Repair if needed).

This should keep Outlook in the old version without auto-switching.

Now, about that horrible Copilot. :(
