Gmail / Google - Browser does not support Javascript when trying to add gmail account to Outlook 365

I am having the same issue with the email tied to the "Organization" account. I have two other personal gmail accounts in outlook that are working fine. The timing of the problem seems very close to the date that google forced the Organization account to either become a paid subscription or opt out of the subscription and keep it fee as it is Personal account. I opted for free personal, because that is what mine is. So could Google now be blocking access to the organization account?

I don't know if this is the cause, but it seems very coincidental.

I am also having this issue and I'm a former Microsoft software engineer! This is an awful glitch. I have tried the following:

• Changing default browser
• Allowing EVERYTHING to go through in Internet Explorer
  • I, too thought they were using the IE component within an application modal, but no changes to IE settings seem to impact it
• I've tried to manually override the login via another copied account, but that didn't work either
• For me, it seems the issue is because I created a Google account with my email, and then I created my GMAIL for it
  • In other words, it gives me that choice of "which account did you want to sign in as" dialog (see image)

In case anybody is still experiencing this issue, using the Google Workspace Sync tool appears to be a workaround: https://tools.google.com/dlpage/gssmo/

Must be using a Google Workspace account though.

I have the same issue and like another poster, had at one time somehow confused Google with a personal gmail version of an email account that is actually under a Google Workspace account so I get the same choice if G-Suite vs Individual. I've seen it before and worked through it before. I can't see how to make the addin for GWSMO work and the help screen seems to say it won't work for Outlook 365 anyway so I didn't go any farther. I am posting here as I have another email account from the same Google Workspace account (different domain) that works fine and when I update the password for it I don't get the browser doesn't support Javascript error...I get a password field as I'd expect.

Perhaps that will help someone solve the problem for all of us. Meanwhile I'm just using another email client. Once Readdle (Support Ukraine!) gets Spark working in Windows I'll end my 30 year unhappy marriage to Outlook for good. It's always been bloated and difficult software.

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).
