Using New Outlook on Windows for personal email, calendar, and contact management
Hi Ed Frost,
Since the error appears to occur repeatedly when New Outlook tries to connect to Gmail, it may be helpful to check whether the Google sign-in flow is being blocked outside of Outlook itself. The current information in the thread does not indicate whether the Gmail account can successfully complete authentication.
You could try these quick checks:
- Sign in to the same Gmail account in your web browser and confirm there are no pending security alerts or verification requests.
- Temporarily sign out of other Google accounts in the browser, then try adding the Gmail account to New Outlook again.
- Open an InPrivate/Incognito browser window, sign in to Gmail there, and then retry the account setup in New Outlook.
If available, please let me know at which stage the failure occurs:
- Before the Google sign-in page appears
- After entering your Google credentials
- After granting Google permissions to Outlook
That detail can help narrow down whether the issue is related to the authentication process or the account connection itself.
Hope this helps point us in the right direction. Let me know if you need further assistance, feel free to ask me by clicking "Add Comment" or "Add Answer" if you cannot add comment so your response will be visible. Thanks for your effort.
