Using New Outlook on Windows for personal email, calendar, and contact management
Hello Brian Brown,
Welcome to the Microsoft Q&A Forum. I understand how frustrating it can be when one email account suddenly stops syncing, especially when another account from the same provider is working without any issues.
This type of sign‑in error usually occurs when the secure web sign‑in (OAuth) process is interrupted during the browser redirect. The steps below often help restore the connection:
- Temporarily disable ad blockers or privacy extensions Some browser extensions can interfere with the sign‑in process. Please disable them briefly, restart Outlook, and try signing in again.
- Temporarily change your default browser Go to Windows Settings > Apps > Default apps and switch to a different browser (for example, Edge to Chrome or Firefox). Restart Outlook and retry the sign‑in. You can switch back afterward.
- Remove and re‑add the account Remove the affected Wix account from Outlook, fully close and reopen the app, then add the account again to refresh the sign‑in connection.
- If using New Outlook, try Classic Outlook New Outlook can be more sensitive with some third‑party IMAP/OAuth configurations. If the issue continues, switching back to Classic Outlook may restore normal syncing.
I hope this helps get your secondary inbox syncing again smoothly.
