If you are unable to reset your Exchange email password due to the requirement of the Authenticator app, here are some steps you can take:
- Check for Alternative Sign-in Methods: If you have any alternative methods for signing in (like SMS verification), try using those to bypass the Authenticator app requirement.
- Contact Microsoft Support: Since you are locked out and unable to use the Authenticator app, contacting Microsoft support is essential. They can assist you in regaining access to your account. You can explain your situation and request help with resetting your password without the Authenticator app.
- Involve Your Organization's Admin: If you are part of an organization, reach out to your IT administrator. They may have the ability to reset your multifactor authentication settings or assist you in regaining access.
- Use the Recovery Form: If you have access to your account briefly, you can try to review your security info and remove any unfamiliar devices or apps associated with your account.
- Create a New Trial Tenant: If you are the sole administrator and cannot reach support, consider creating a new trial Microsoft 365 tenant. This will allow you to sign in to the Admin Center and raise a support ticket directly from there.
These steps should help you address the issue of resetting your password without the Authenticator app.
