"Keep Me Signed In" not working

Dear Joseph R S, 

Thank you for reaching out to the Microsoft Q&A Community. I understand that you are having trouble with the Outlook app on Android repeatedly asking you to sign in, even after selecting “Keep me signed in.” I’m happy to assist you with this. 

This issue typically occurs due to token expiration, account type mismatch, or device settings that prevent Outlook from maintaining its session. Please follow these detailed steps: 

1. Confirm Account Type 

For Microsoft 365 accounts provided by GoDaddy, ensure they are added as Work or school accounts (not Personal). If they were added incorrectly, remove and re-add them using GoDaddy’s instructions: 

• Open Outlook. 
• In the upper-left corner, tap the account menu, and then Settings. If you're a new user, tap ADD ACCOUNT, and then skip to step 4. 
• Tap Accounts, Add account, and then Add an email account. 
• If you see a prompt that says your email is used with more than one account with Microsoft, tap Work or school account (not Personal account). 
• Enter your email password, and then tap Sign In.
• If you're signing in from a new device or location, you'll see a prompt to Verify it's you and confirm your identity through a one-time code.  
• If you're asked to trust your domain, tap Continue.  
• If it's your first time signing in and multi-factor authentication (MFA) is enabled, you'll see a prompt to set up your authentication method. 
• If you already have MFA set up, verify your identity using your authentication method. 
• You might get a request for permission to access your account, tap Accept. 

2. Update Outlook and Clear Cache/Data 

• Open Google Play Store, update the Outlook app to the latest version. 
• Go to Settings > Apps > Outlook > Storage > Clear Cache and Clear Data. 
• Reopen Outlook and sign in again.

3. Install and Update Microsoft Authenticator 

Outlook uses Microsoft Authenticator as an authentication broker. Keeping it installed and updated reduces repeated prompts:

4. Disable Battery Optimization and Data Saver for Outlook 

On Android, battery optimization or data restrictions can interrupt token refresh.  

• Go to Settings > Battery > Battery Optimization and exclude Outlook (and Microsoft Authenticator). 
• Ensure Data Saver is off or Outlook is allowed unrestricted data usage. 

5. Understand Session Behavior 

“Keep me signed in” does not guarantee indefinite sign-in. Microsoft 365 sessions rely on tokens that can expire due to inactivity, password changes, or policy updates: 
See: Session timeouts for Microsoft 365 - Microsoft 365 Enterprise | Microsoft Learn 

6. Use In-App Support if Issue Persists 

If the problem continues, please use Settings > Help & Feedback > Contact Support in the Outlook app to submit diagnostics: Get in-app help for Outlook for iOS and Android - Microsoft Support
