If you are unable to access your school email due to issues with the authentication app after getting a new phone, you can follow these steps:
- Alternative Verification Methods: If you have set up other options for security verification, try selecting Other verification options on the sign-in page. This may allow you to use a different method to verify your identity.
- Contact Support: If you are the only administrator for your account, you may need to contact Microsoft support for assistance. They have tools to help verify your identity and regain access to your account. Look for the customer service phone numbers for Microsoft Support in your region.
- New Trial Tenant: As a last resort, you could set up a new trial tenant to submit a support request. This will allow you to contact Microsoft support without accessing your original account. However, this new tenant will not give you access to any data from your original account.
- Check Account Settings: If you have access to another admin account, ask them to check if your phone numbers are set correctly in your user account settings.
These steps should help you regain access to your school email account.
