Question details
Outlook on iPhone repeatedly asks for Microsoft Authenticator approval after a password reset, but no prompt appears.
- Product
- Microsoft Authenticator / Outlook
- Device & OS
- iPhone
- Scenario
- Accessing the Outlook mobile app after changing the Microsoft 365 account password.
- Observed behavior
- An endless approval loop occurs where Outlook requests authentication, but the Authenticator app fails to display the required approval prompt.
Ensure you have access to a secondary authentication method, such as SMS or a backup email, before making changes to your Microsoft Authenticator app settings.
Seek Specialized Help in the Microsoft Authenticator Community
Because this is primarily an Authenticator and MFA issue rather than an Outlook app error, reaching out to Microsoft specialists is the most effective approach.
Authentication loops on mobile devices often require backend account resets or specific token refresh procedures that only Microsoft administrators or community specialists can guide you through.
Open your web browser and navigate to the official Microsoft Tech Community forums, specifically the Microsoft Authenticator section.
Create a new post explaining that you are stuck in an approval loop after a password change. Be sure to include your device (iPhone), account type (e.g., Microsoft 365 Business), and any available verification methods.
Monitor your post for replies from Microsoft MFA specialists who can provide targeted troubleshooting steps for your specific account setup.
Refresh Your Authenticator Connection
Removing and re-adding your account in the Authenticator app can force the system to generate new authentication prompts.

Frequently Asked Questions
Why is my Microsoft Authenticator not showing approval prompts?
This often occurs if push notifications are disabled for the Authenticator app in your iPhone settings, or if the connection between the app and your Microsoft account needs to be refreshed after a recent password change.
Can I access Outlook on my iPhone without using Microsoft Authenticator?
If your organization mandates Multi-Factor Authentication (MFA) via Conditional Access policies, you must use an approved authentication method like the Microsoft Authenticator app, a text message code, or a phone call to access Outlook.
How do I change my default MFA method if I am locked out?
