Answer 1

Tom,

Is your company using Office Subscription or is it a perpetual license? For example, if you go to http://portal.office.com/ can you log in with your work account? This should work for Office Subscription. If you have Office Subscription, see if you have In App support by clicking Help, Contact Support and submit a ticket this way.

Double check both paths have the registry key as shown in the article, Error 'This web browser does not support JavaScript or scripts are being blocked' when adding a Google Workspace account - Microsoft Support.

Primary:

Computer\HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BROWSER_EMULATION

Secondary:
Computer\HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BROWSER_EMULATION

Thank you as well, it worked! I just purchased a new LG Ultra 17" laptop. It came preloaded with Windows 11 Home which I immediately upgraded to Windows 11 Pro. I have 3 separate emails through my internet provider Telus. One account I was able to connect with no issues. When I went to add the second account, I got the JavaScript error. Telus support was no help, after being on hold for an hour, they said to call Microsoft Support and gave me Microsoft's support number which they must have had memorized. I called Microsoft support, got a recording that gave me a link to Microsoft main help page which was useless. I DuckDuckGo'd the error message and it brought me directly to this page. After scrolling through all the comments/replies I came to this instruction. Followed the step-by-step instructions and was able to add my other two emails with no errors.

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.

Hi Brian,

No I don't have 2 factor enabled - would that make a difference to the Javascript issue I'm having?

The outlook guide above is what I loaded first, however being Outlook was not even "setup" I was straight at step 2 and still trying to work out what "Mini browser" the "Outlook App" uses in the setup phase?

Outlook automatically finds my account (email address) I wish to setup, I then choose the option between Business and Personal (Business) then get the Javascript error
