Using Outlook for Android in business environments for email and scheduling
Hi @Mateusz Janczak
Thank you for posting your question in the Microsoft Q&A forum.
Based on your description, it looks like you’ve already tried several appropriate troubleshooting steps without success. To help narrow down the issue, could you confirm whether you’re able to access https://login.microsoftonline.com in your mobile browser? This will help determine if the login page itself loads normally or if the same blank screen issue occurs there as well.
From what I’ve found, other users have also reported seeing a blank or white screen when signing in to Microsoft Work or school accounts on devices running Android 14. Since you've already tried many of the recommended steps, the best next step is to submit a support ticket through the Microsoft 365 admin center so that Microsoft Support can investigate further.
Since only a Global Admin can open a support case, you’ll need to reach out to your organization’s IT administrator to proceed.

I hope this helps.
