Using Classic Outlook on Windows for personal email, calendar, and contact management
Hi Morris,
Please be advised that there is an ongoing Microsoft 365 service disruption affecting Outlook and Exchange Online connectivity. This may also be affecting the Outlook account configuration process you are experiencing.
Although we cannot confirm that the issue is directly caused by the ongoing outage, we recommend waiting until Microsoft has restored the affected services before attempting to add or configure your Gmail account again.
Once the service disruption is resolved, please try setting up your account again. If the issue persists, we can proceed with further troubleshooting to identify the cause of the authentication error.
We appreciate your patience and understanding while Microsoft works to restore the affected services
