Users are experiencing password rejection in Microsoft Office iPhone apps such as Outlook and Teams, even after successfully updating to a correct new password.

How to Fix Microsoft Office Password Errors on iPhone After Changing Password

Product: Microsoft Office, Outlook, Teams
Device & OS: iOS
Scenario: Attempting to use Microsoft Office apps on an iPhone after recently updating the Microsoft account password.
Observed behavior: The mobile applications continue to use outdated authentication tokens, causing them to reject the new, correct password while browser logins work perfectly fine.

Before you start

Verify your new password is correct by signing into the Microsoft Office portal (portal.office.com) via a mobile or desktop web browser. Ensure you have a stable internet connection before attempting to re-authenticate your mobile apps.

Solution 1Recommended

Remove and Re-add the Account in iPhone Apps

Clearing the account from your device forces the app to drop outdated tokens and request a fresh authentication.

Often, iOS apps hold onto old session tokens even after a password change. Removing the account locally forces the app to connect to Microsoft's servers and request new credentials.

Open account settings

Launch the affected app (e.g., Outlook) on your iPhone, tap your profile icon in the top left, and navigate to the Settings gear icon.

Delete the account

Select the email account that is experiencing the password error and tap 'Delete Account' at the bottom of the screen. Confirm the deletion.

Re-add the account

Restart the application, tap 'Add Account', and sign in using your updated Microsoft account password.

Data Safety: Deleting the account from the app will not delete your emails or files from the server. They will resync once you log back in.

Solution 2

Delete and Reinstall the Affected Microsoft Apps

If removing the account doesn't work, completely reinstalling the app clears all cached data and stubborn authentication tokens.

Solution 3

Reset Password via Office Portal or Contact Admin

Sometimes the account requires a fresh sync from the server side, or your organization's IT policy is blocking the login.

Frequently Asked Questions

Why does my iPhone keep rejecting my new Microsoft password?

iPhone apps like Outlook and Teams often cache authentication tokens to keep you logged in. When you change your password, these old tokens become invalid, causing the apps to reject the new password until the cache is cleared or the account is re-added.

How do I know if my Microsoft account password is actually working?

You can verify your password by logging into portal.office.com using a web browser like Safari or Chrome. If you successfully log in there, your account and password are correct, and the issue is isolated to the mobile apps.

Will deleting the Outlook app on my iPhone delete my emails?

No. Your emails, calendar events, and contacts are stored securely on Microsoft's servers, not locally on your iPhone. Once you reinstall the app and sign back in, all your data will sync back to your device automatically.

What should I do if the 'Forgot password' option is missing or disabled?

If you are using a corporate or school account, your organization may have disabled self-service password resets for security reasons. You will need to reach out to your IT support desk or administrator to have your password reset.
