Dear @Yash Machhi (US),

Thank you for providing the information. Could you please help me check the items below? I want to determine whether the issue you're experiencing is caused by your app or your account. Please help me perform the steps and report back to me. Once we know the exact cause, we can proceed with the correct troubleshooting steps:

Please sign in to Outlook on the web to see whether everything works normally or if the same issue occurs.

Please try logging in on a different device (another laptop) to check whether it displays normally.

Do your colleagues see the modern themes displayed correctly?

Please help me perform an online repair according to these instructions Repair an Office application - Microsoft Support.

Please help me uninstall and reinstall the app.

If the issue persists, please help me create a new Windows profile, download the new Outlook on the new Windows profile, and check if the same issue occurs Manage User Accounts in Windows - Microsoft Support.

Please answer all the questions above completely. From there, I will be able to determine whether the issue comes from your account, the app, or your device.

Hello, no answer will help you...it's a big issue from Microsoft, et no explaination, even with the support. I have E5 with all features and Copilot option, i set modern copilot theme in my outlook and outlook on my IPhone. ,All working fine !

And after a few days, modern theme and copilot theme totally disappeared for me and 1300 users, and more for many cutomers, even in OWA...but still work on IPhone.

we can't do anything..it's really a big problem in MS side, and i can confirm because of all customers who call us to try to undertstand....

We try in admin center to check if all is OK, and it is (validation from support)...

no solution

To change the theme, navigate to the Appearance settings within the application.
Under the Dark mode section, select from 'Light', 'Dark', or 'Use system settings'.
In the Themes section below that, different color options are available to choose from.

Dear @Yash Machhi (US),

Thank you for posting your question in the Microsoft Q&A forum.

The new Outlook is web-based, so please help me check how the modern themes currently display on your current web version and provide a screenshot.

Please help me click on Settings > General > About Outlook > and take a screenshot of the version you are currently using.

Please try logging in on a different device (another laptop) to see if it displays normally.

I see you tagged it as 'for business,' is this a work account? If so, do your colleagues see the modern themes displayed normally?

Please help me perform an online repair according to these instructions Repair an Office application - Microsoft Support.

Please help me uninstall and reinstall the app.

If the issue persists, please help me create a new Windows profile, download the new Outlook on the new Windows profile, and check if the same issue occurs Manage User Accounts in Windows - Microsoft Support.

Please help me answer all the questions above fully and provide the results of the three steps (online repair, uninstall - reinstall and create new Windows profile). From there, I will be able to determine if the error is due to your account, the app, or your device.

Looking forward to your response!
