Not able to sign in teams in my mobile phone?

Hello Microsoft Support,

I’m experiencing an issue signing in to the Microsoft Teams mobile app using my personal Microsoft account (part of a Microsoft Family group).

  • I can successfully sign in to Teams on my computer and browser at teams.live.com, where I can access chats, calls, and settings.
  • Other Microsoft apps like Word and OneDrive work perfectly on my mobile phone.
  • However, when I try to sign in to the Teams mobile app, I receive the error: “Sorry, but we're having trouble signing you in, please try again.”
  • This happens immediately after entering my email address, and I do not see any account type selection screen.

I’ve already tried the following:

  • Reinstalling the Teams app
  • Restarting my phone
  • Clearing cache and data (Android)
  • Ensuring my account is active and verified
  • Signing in via browser (which works fine)

Could you please help me resolve this issue or check if there’s a block or misconfiguration preventing mobile sign-in for my account?

Thank you in advance for your assistance.

    Dear Choi Au-Yeung,

    Thank you for reaching out to Microsoft Q&A forum 

    I completely understand your issue you are facing when you cannot sign in Microsoft Teams on your mobile.  

    To help you resolve this, please try the following steps: 

    1. Check Date and Time settings 

    Ensure your phone’s date and time settings are accurate. Microsoft Teams relies on correct time settings to authenticate properly 

    2. Sign in via Mobile Browser (Desktop Mode) 

    • Open Chrome or another browser on your mobile device 
    • Go to Sign In | Microsoft Teams 
    • Tap the menu and select “Desktop site” 
    • Try signing in and check if you can access Teams 

    3. Try Resetting Your Password 

    • Go to the Teams sign-in page on your computer, click “Forgot password?”, and follow the instructions to reset your password. 
    • After resetting, try signing in again on your mobile device. 

    4. Use Microsoft Authenticator (if MFA is enabled) 

    If you haven’t linked Microsoft Authenticator to your account yet, please do so: 

    I'm here to help if you need further assistance or if these steps don’t work. Please let me know, and I’ll guide you through the next steps.
