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

Do this, worked for me:

1. From the Start menu, type regedit.exe in the search box, and then press Enter.

If you are prompted for an administrator password or for confirmation, type the password or provide confirmation. 2. In Registry Editor, navigate to: HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BROWSER_EMULATION 3. Find the REG_DWORD OUTLOOK.EXE and double-click to edit. 4. Select Decimal and change it to 11001 and select OK. 5. Close Registry Editor and restart Outlook.

MichaelVorst,

THANK YOU!!! It worked!!

I do wonder why this problem started in the first place. Did something change the Value Data...or did some update to Outlook make it no longer work with what had been there....and hoping the issue does not come back.

Thank you for your super clear and easy to follow directions. So glad to have that nuisance resolved.

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.

I have similar problem. I have Windows 10 and Microsoft Office Home and Business 16 (all fully updated). Yesterday evening 8/15/22 Outlook asked me to sign back into Google to fetch my email.

I enter my email address.

I select Organizational Account.

Then I get the message "the browser you are using doesn't support JavaScript, or has JavaScript turned off. Too keep your account secure, try signing in on a browser that has JavaScript turned on" Learn More....."

I click on "Learn More" and an unhelpful info page would open in Internet Explorer.

My Default Browser is Chrome. And JavaScript is enabled.

I reset everything rebooted my computer...same thing. I Uninstalled Internet Explorer and now I don't get the unhelpful "Learn More" page.

I tried making Microsoft Edge my default browser and confirmed JavaScript was on. Same thing...

Rebooted every time I made a change.

The other email that is I have on Outlook is a Microsoft 365 account my work gave me and it is working fine.

I, of course can work around by keeping by browser open to my Gmail account...but not ideal.

Thanks!

By any chance are you using an HP computer or laptop? Since I only have this problem on my HP laptop and not my Asus, I’m wondering if this is the issue. Also, on this laptop only, Outlook keeps dropping my iCloud add in and won’t let me get it back without tech support.
