How to Fix Repeated Exchange Password Prompts on iPhone
Question details
The user is repeatedly prompted to enter their Exchange account password on an iPhone, despite entering the correct Microsoft 365 or Outlook.com credentials.

- Product
- Microsoft Exchange / Outlook.com
- Device & OS
- iPhone
- Scenario
- Accessing email inboxes through the mail client on an iPhone.
- Observed behavior
- A 'wrong password for your Exchange account' message persistently appears on the iPhone, even after resetting the password and verifying that the account works properly on a Windows laptop.
Verify that you know your current Microsoft account password and ensure your iPhone is connected to a stable Wi-Fi or cellular network before making changes to your account settings.
Remove Obsolete or Inactive Exchange Accounts
If you previously connected an organizational or charity account that is no longer active, removing it from your iPhone can permanently stop the repeated password prompts.
Often, forgotten or expired accounts from past affiliations (such as retired work or charity accounts) remain cached on the device. When the iPhone attempts to sync with these inactive servers, it continuously prompts for a password.
Navigate to the home screen of your iPhone and tap on the 'Settings' app.
Scroll down and tap on 'Mail', then select 'Accounts' to view all email accounts linked to your device.
Review the list for any old work, school, or charity Exchange accounts that you no longer have active access to.
Tap on the obsolete account and select 'Delete Account' to remove it from your iPhone.
If you accidentally removed your personal account, tap 'Add Account', select 'Microsoft Exchange' or 'Outlook.com', and sign back in using your current credentials.

Check Microsoft Service Health and Contact Support
Unexpected Exchange password prompts can sometimes be caused by server-side issues or ongoing Outlook.com outages.

Frequently Asked Questions
Why does my iPhone keep asking for my Exchange password even when it's correct?
This commonly happens when an obsolete or inactive account (such as a previous work or charity account) is still linked to your device, when server settings have changed, or when there is an ongoing Microsoft service outage.
Does resetting my Microsoft password fix the Exchange prompt on my iPhone?
Not always. If the issue is caused by a disconnected organizational account or a server glitch, a password reset will not resolve the prompts until the problematic account is removed from your device or the service outage is resolved.
How do I remove an old work or charity Exchange account from my iPhone?
Go to Settings > Mail > Accounts on your iPhone, select the obsolete Exchange account from the list, and tap 'Delete Account' to remove it and stop the authentication prompts.
What should I do if Outlook.com is experiencing an outage affecting iOS?
If Microsoft officially reports an outage affecting Exchange connections on iOS, you will need to wait for their engineering team to resolve the server-side issue. You can monitor the status via the Microsoft Service Health dashboard.
