How to Fix 'Action Required' Messages in Outlook on Desktop and iPhone

Product: Microsoft Outlook
Device & OS: Desktop (Windows/Mac) and iOS (iPhone)
Scenario: Syncing or retrieving new emails across desktop and mobile devices.
Observed behavior: Outlook displays an 'Action Required' message during email retrieval, halting the synchronization process for both desktop and iPhone apps.

Before you start

Verify whether your email is a personal account (like Outlook.com or Hotmail) or a Microsoft 365 Business account, as the troubleshooting channels and security settings differ significantly.

Solution 1Recommended

Troubleshoot 'Action Required' for Microsoft 365 Business Accounts

Follow these steps if your email is provided by your employer, school, or managed via a company Microsoft 365 administrator.

Business accounts have security policies enforced at the organizational level. When Outlook prompts for action, it typically means a password has expired, multi-factor authentication (MFA) requires re-verification, or a conditional access policy has blocked the device.

Verify recent security changes

Recall if your organization recently mandated a password change or implemented a new Multi-Factor Authentication (MFA) app. If so, log out of Outlook on your iPhone and Desktop, then sign back in using the new credentials.

Contact your Microsoft 365 Administrator

Reach out to your company's IT support desk. Request that they check your account status in the Microsoft 365 Admin Center under 'Users' > 'Active users' to ensure your license is valid and not locked.

Submit a business support ticket

If the IT administrator cannot resolve the sync block, ask them to navigate to 'Support' > 'Help & support' within the Microsoft 365 admin center to escalate the issue directly to Microsoft Business Support.

Troubleshoot 'Action Required' for Microsoft 365 Business Accounts

Information Gathering: When contacting IT or support, provide the exact wording of the 'Action Required' message and specify that the issue occurs on both desktop and iOS devices.

Solution 2

Fix 'Action Required' for Personal or Family Accounts

Use this method if you are using a free Microsoft account (Outlook.com, Hotmail.com) or a Microsoft 365 Family subscription.

Frequently Asked Questions

Why does Outlook continuously say 'Action Required' on my iPhone?

This generally indicates an authentication token has expired, your account password was recently changed, or Microsoft has flagged your login as a security risk requiring manual verification on their website.

Can my IT administrator fix my personal Outlook.com email?

No, company IT administrators only have access to the Microsoft 365 Admin Center for business accounts. For personal Outlook.com or Hotmail accounts, you must manage your security settings yourself at account.microsoft.com or contact Microsoft consumer support.

How do I know if my Microsoft account is a business or personal account?

Personal accounts typically end in @outlook.com, @hotmail.com, or are registered as Microsoft 365 Family subscriptions. Business accounts use a custom company domain (like name@yourcompany.com) and route you through an organizational sign-in page when accessing office.com.

Does updating the Outlook app fix the 'Action Required' error?

While updating the app from the App Store or updating the desktop client can resolve software bugs, an 'Action Required' prompt is almost always related to account credentials and security policies rather than the app version itself.
