Sending, receiving, and organizing email in Outlook on the web for business
Hello Kalyndra,
Thank you for choosing the Microsoft Community! We are happy to help you.
I understand you use Outlook on the Web in dark mode, but when you reply to emails, they are being set to white instead of automatic making it difficult to read for recipients that are not using dark mode. Please correct me if I am wrong.
To help us narrow down this issue kindly try the troubleshooting steps below and let us know the result for further troubleshooting:
- Kindly log in on a different browser and check if the issue persists. You can also log in via private/incognito mode.
- Clear browser cache: for Microsoft Edge see How to Clear Your Cache - Microsoft 365, for Chrome check this link from Google link.
May I know if this is happening with all users you are sending emails to?
We look forward to hearing from you; Please understand that our initial reply may not always immediately resolve the issue. However, with your help and more detailed information, we can work together to find a solution. Thank you for your cooperation.
Sincerely,
Simbarashe | Microsoft Community Moderator
