I’m unable to add my university Office 365 email to Outlook or Teams on my Android phone, as the screen goes white after entering my email, even though it works fine on my PC and I’ve reinstalled the apps.

Dear @Umair Shahzad,

Welcome to Microsoft Q&A Forum!

Based on your description, it sounds like you’re encountering a frustrating blank or white screen when signing in to your Microsoft work or school account on an Android device. This issue may cause by factors such as corrupted app cache, network connectivity problems, or outdated Android system components. Therefore, I have several suggestions that you can try to see if they may help:

First, please try accessing Outlook and Teams via the web: outlook.office.com and teams.microsoft.com on your mobile browser. If these work fine, you can use them as a temporary workaround while we address the app issue.

For the Android apps, here are steps to check:

1.You need clear Microsoft App Cache and Data:

• Go to Settings on your Android phone.
• Navigate to Apps or Application Manager.
• Find and select the Microsoft Teams and Outlook
• Select Storage.
• Clear Cache and then clear Data (or clear Storage). Note: This action will reset the app to its default state, and you will need to sign in again.
• Restart the app and attempt to sign in. 

2.You should check to update Android System Webview and Chrome browser: Microsoft apps often rely on Android System Webview to display the sign-in page. If this component is outdated, the screen may appear blank.

• Open the Google Play Store.
• Search for Android System Webview and Google Chrome.
• Ensure both applications are updated to the latest version.

3.You should check connection and restart device:

• Switch networks: If you're on Wi-Fi, try switching to mobile data (4G/5G) and vice versa. You should ensure your connection is stable.
• Restart device: Completely turn off your Android phone, wait about 30 seconds, and turn it back on. Then, try signing in again.

4.You may need to uninstall and reinstall the App:

If clearing the cache doesn't work, a fresh installation may resolve any corrupted installation files.

• Uninstall the problematic Microsoft app from your phone.
• Restart your phone.
• Go to the Google Play Store and reinstall the app.
• Attempt to sign in with your work or school account.

It sounds like you're experiencing a common issue with adding accounts to Outlook and Teams on Android devices. Here are some steps you can take to troubleshoot the problem:

1. Turn Off Battery Optimization: Ensure that battery optimization is turned off for both Outlook and Teams. This can sometimes interfere with app functionality.
2. Change App Launch Settings: Set the launch settings for Outlook and Teams from "Automatic" to "Manage Manually". Enable the options for auto-launch, secondary launch, and run in background.
3. Data Saver Settings: If you have Data Saver enabled on your device, make sure to allow unrestricted data usage for both Outlook and Teams.
4. Enable Notifications: Ensure that notifications are enabled for both apps, as this can sometimes affect their performance.
5. Collect Diagnostic Logs: If the issue persists, you can collect diagnostic logs from Outlook for further investigation. Go to Outlook settings, tap on "Help & Feedback", then "Collect Diagnostics" to gather logs that can be shared with support.

If none of these steps resolve the issue, you may want to consider reaching out to Microsoft Support for further assistance.
