Answer 1

Please try the workaround guidance in this Outlook Known Issue article, Error 'This web browser does not support JavaScript or scripts are being blocked' when adding a Google Workspace account (microsoft.com).

Answer 2

I had the same issue but after some further digging I have now been able to resolve the issue. Follow the instructions below

1. Open Registry Editor and navigate to: HKEY_CURRENT_USER\Software\Microsoft\InternetExplorer\Main\FeatureControl\FEATURE_BROWSER_EMULATION (you can copy and paste this text into the navigation bar at the top)
2. Then double click on OUTLOOK.EXE
3. When the pop-up window appears first select Decimal
4. Then under the Value Data change the value to 11000
5. Close the Registery window and close down Outlook (if not done previously). You should then be able to login as normal with either the Individual or G-Suite account.

Answer 3

I have the same problem, except that I am running Windows 10. Can no longer use my gmail account through Outlook, as Google keeps telling me that "the browser you're using doesn't support JavaScript..." except that my default browser is Chrome, with JavaScript turned on.

I had a similar issue was resolved by following the fix mentioned in the link below. This fix has to do with a registry change for Microsoft outlook

Everything works the way it should.

Answer 5

No not via the normal auto setup way - it happens on my main admin account with 20 yrs plus of emails :( - works on any other of my families accounts (admin included)..

HOWEVER - and still doing a test as to how effective this is - I found a work around:

Google workspace to outlook sync tool - all emails for me work flawlessly including adding folders (labels) moving into folders etc, contacts did not sync however.
