Sending, receiving, and organizing email in Outlook.com
Since the Microsoft account itself still works, the immediate issue is likely with Outlook on iPhone or the iPhone Mail app authentication.
Try these steps in order:
- Check whether Outlook.com is having a service issue.
- If the service status is not green, wait and try again later.
- If the problem is in the iPhone Mail app, re-enter the account password in iOS:
- Open Settings on the iPhone.
- Tap Mail.
- Tap Accounts.
- Select the Outlook/Hotmail account.
- Tap Account Settings or the Password field.
- Enter the correct or updated password.
- Tap Done.
- Open the Mail app and confirm mail is syncing and messages can be sent and received.
- If the account was removed and cannot be added back in the iPhone Mail app, first recover sign-in access if needed:
- Use the Sign-in Helper tool.
- If the password is known but stopped working, use the recovery flow:
- Enter the email address, phone number, or Skype name.
- Choose where to receive the security code.
- Enter the code.
- Set a new password.
- If using the Outlook mobile app instead of Apple Mail:
- Install the latest version of Outlook mobile, because recurring password prompts can happen when app security standards are updated.
- If the password was recently changed:
- Outlook for iOS may show a sync error and ask for the password again.
- If Outlook for iOS still does not sync with the new password, delete the email account from Outlook for iOS and add it again.
- If the username is not recognized or the account still cannot be found:
- Verify the correct email domain is being used, such as .com vs .co.uk.
- Check the email name spelling carefully.
- If another alias or phone number exists on the account, try that instead.
- If sign-in works but Outlook.com mail still does not load in the browser:
- Check the Outlook.com service status and try again after service returns to normal.
If the specific symptom on iPhone is “Account not authenticated” or “Cannot Get Mail – The connection to the server failed”, the iOS Mail password re-entry steps above are the documented fix.
