Using New Outlook on Windows for personal email, calendar, and contact management
If Outlook on the web works but Outlook desktop does not, use this order:

- If the wrong account type is being used, sign out and sign in again with the correct account.
- If Outlook desktop shows “You can't sign in here with a personal account. Use your work or school account instead.”
- This is a known issue that was fixed in Version 2303 Build 16227.20202 and higher.
