Answer 1

Gabriel,

Sorry, was out of town for a while. The issue I am having is that the file you are asking to edit does not exist. Here is a screen shot. This is on my work computer. On my home desktop, the file did exist and I was able to fix the problem per your instructions. Any ideas about my work computer? Do I need to reinstall outlook? Something else?

Worked for me: https://support.microsoft.com/en-gb/topic/error-this-web-browser-does-not-support-javascript-or-scripts-are-being-blocked-when-adding-a-google-workspace-account-b7cbc25e-5b2d-459a-97b8-c8b6adc7b2d4

A simple Reg Edit

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.

Worked perfectly. Thanks.

Answer 4

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)

Hi. I'm Brian and I will do my best to help you.

Do you have two-factor authentication enabled in your Google account?
