Adding Gmail account to Outlook MacOs

It sounds like you're experiencing an issue with adding your Google account to Outlook on macOS, specifically with the authentication loop. Here are some steps you can try to resolve the issue:

1. Check Browser Settings: Ensure that your default browser is set correctly in your macOS settings. Sometimes, Outlook may rely on the default browser for authentication.
2. Clear Browser Cache: Clear the cache and cookies of the browser you are using. This can help eliminate any stale authentication data that might be causing the loop.
3. Try a Different Browser: If you're not using Safari, try switching to another browser like Chrome or Firefox to see if the issue persists.
4. Disable Extensions: If you have any browser extensions, particularly those related to privacy or security, try disabling them temporarily to see if they are interfering with the authentication process.
5. Update Outlook: Make sure that your Outlook application is up to date. Sometimes, bugs in older versions can cause issues with account connections.
6. Re-add the Account: Remove the Google account from Outlook and try adding it again. Make sure to follow the prompts carefully during the authentication process.

If these steps do not resolve the issue, you may want to consult Microsoft support for more specific troubleshooting related to your version of Outlook and macOS.

Worked through it with Safari: yelow dot, no contact with Gmail/Google so: no contacts.

Everything is much to complicated.
