Why is the Gmail app saying that my Microsoft account doesn't exist?

Dear @Washington, Vivianna

Thank you for posting your question in the Microsoft Q&A forum. I understand you're encountering issues when trying to add your Microsoft school-provided email to the Gmail app on iOS.  

To better understand and solve the problem you are facing, could you help me with the following? 

• Are you able to log in to your Microsoft account on a different device (like a computer)? 
• Have there been any changes made to your school account settings recently? 
• What specific device and operating system are you using for the Gmail app? 

Based on recent testing, we’ve observed that on Android devices, signing in with a school-provided Microsoft account typically works when selecting Exchange and Office 365 as the account type.

However, this sign-in method currently appears to be disabled or unsupported on iOS, which may explain the issue you're experiencing.

For detailed instructions, you can refer to the official Microsoft support article: Set up email in Android email app

In the meantime, here are a couple of options depending on what you want to do: 

1. Account Type Selection 

• If your email is provided by a school or organization, it is likely a Microsoft 365 (Work or School) account. 
• Please ensure you're selecting Office365 (not Outlook/Hotmail/Live) when adding the account in Gmail. 

2. "Account Doesn't Exist" Error 

• This may occur if the account is not recognized as a personal Microsoft account. School accounts are managed by your institution and may require specific configurations. 
• If you see this error, try signing in at https://portal.office.com to confirm the account is active. 

3. "Incorrect Username or Password" Error 

• If you're sure the credentials are correct, your school may require additional security settings or app passwords. 
• Please contact your school’s IT administrator to confirm: 
  • Whether IMAP/SMTP access is enabled. 
    • If multi-factor authentication (MFA) or conditional access policies are in place. 

4. Troubleshooting Steps 

• Try using the Microsoft Sign-in Helper Tool to diagnose account issues: I can't sign in to my Microsoft account - Microsoft Support 
• If you're trying to connect Gmail to Outlook, ensure IMAP is enabled in Gmail settings: Fix problems connecting your Google account to the Microsoft Cloud - Microsoft Support 

Confirm with your IT admin that your account is active and properly configured for third-party email apps. 

If the issue persists, consider using the Outlook mobile app, which is optimized for Microsoft 365 accounts. 

Please let me know if you need further assistance.
