Managing personal Outlook.com account settings, security, and privacy
Try removing the stuck account entry and then add the account back from inside Outlook.
- In Outlook on the iPhone, open Settings.
- Select the affected account.
- Tap Delete Account.
- Close Outlook, then reopen it.
- Add the account again.
If the account was previously changed or Outlook is holding old sign-in details, deleting and re-adding the account imports the correct settings again.
If the problem is with an old work account still being managed on the device, check iPhone Settings > General > VPN & Device Management and remove the old company management profile before adding the account again. This can affect access to Outlook and other Microsoft apps.
If Outlook still shows sign-in problems after that:
- For a personal Microsoft account, use the Microsoft sign-in helper tool.
- If Outlook shows "account disconnected", sign in again when prompted.
- If the issue started after a password change, change the password on the email provider’s website first, then re-enter it in Outlook. If sync still fails, delete the account and re-add it.
