Product: Microsoft Outlook
Device & OS: iPhone (iOS)
Scenario: Trying to check new emails or sync an Outlook account on an iPhone.

Solution 1Recommended

Remove and Re-add Your Outlook Account

Resetting the connection between your device and the email server is the most effective way to clear persistent authentication loops.

This process will not delete your emails, as they remain safely stored on Microsoft's servers. Re-adding the account forces the app to generate a fresh, secure authentication token.

Open account settings

Launch the Outlook app on your iPhone, tap your profile icon in the top left corner, and select the Settings (gear) icon at the bottom left.

Delete the account

Tap on the problematic email account under the 'Mail Accounts' section, scroll to the bottom, and select 'Delete Account'.

Re-add the account

Restart the Outlook app, go back to Settings, tap 'Add Mail Account', and follow the on-screen prompts to sign in with your email address and password.

Data Safety: Your emails, contacts, and calendar events will automatically sync back to your iPhone once you sign in again.

Solution 2

Restart Your iPhone

A simple device restart can clear temporary network glitches or background app conflicts causing the password prompts.

Solution 3

Uninstall and Reinstall the Outlook App

If the app is corrupted or experiencing bugs, a fresh installation from the App Store can fix underlying software issues.

Frequently Asked Questions

Why does my iPhone keep asking for my Outlook password?

This issue typically occurs due to an expired authentication token, a temporary sync error with Microsoft's servers, or an outdated email application.

Will removing my Outlook account from my iPhone delete my emails permanently?

No. Your emails are stored securely on Microsoft's cloud servers. Deleting the account from your iPhone only removes the local sync data; everything will download again when you sign back in.

How do I fix this if I am using the native iOS Mail app instead of the Outlook app?

If you use the built-in Apple Mail app, go to your iPhone Settings > Mail > Accounts. Tap your Outlook account, select 'Delete Account', and then add it back by choosing 'Outlook.com' or 'Exchange' from the Add Account menu.
