White screen Android device about Teams, Outlook and Onedrive

Hi Alex,

When Microsoft 365 apps like Outlook, Teams, and OneDrive consistently drop to a white screen immediately after you enter your company email and click Continue, it almost always points to a breakdown in how the app renders the OAuth authentication handoff typically governed by Android System WebView or underlying browser cache issues.

Because standard cache clearing and reinstalls haven't resolved it, try clear Android System WebView and browser cache out of stubborn rendering tokens:

• Go to your Android Settings > Apps.
• Locate Android System WebView (and Google Chrome or any browser you use as default browsers).
• Tap Storage, then select Clear Cache (do this for both).

If your company enforces mobile device management (MDM) or Conditional Access Policies, check if an accompanying app like Microsoft Intune Company Portal or Microsoft Authenticator needs an update, or if a pending compliance check is hanging silently in the background.

However, since this behavior spans multiple Microsoft apps on your device despite clean reinstalls, the issue requires a backend look or escalation.

Given the nature of the problem, the most effective next step is reaching out to your IT admin and ask them to use their admin credentials to submit a support request through the Microsoft 365 Admin Center on your behalf.

Microsoft also provides customer service phone numbers based on your region. Your IT admin can find the appropriate contact number here: Customer service phone numbers - Microsoft Support 

This route ensures that a Microsoft support engineer can initiate a remote session to investigate backend configurations, run advanced diagnostic tools, and, if necessary, escalate the case to specialized teams with access to internal systems and logs. These backend resources are essential for resolving issues that go beyond what’s visible in the user interface.

As community advisors, I'm here to guide you, but due to privacy and security limitations, I don’t have access to the backend tools required for a full resolution. For this reason, contacting Microsoft Support via the Admin Center is the most secure and efficient way forward.

In case you do not know who is your IT admin, kindly refer to this article: How do I find my Microsoft 365 admin? - Microsoft Support 

I hope this helps you resolve the issue quickly. I’m glad to assist and truly hope the information provided has been useful. Please feel free to reach out anytime if you need further assistance.
