Using classic Outlook for Windows in business environments
Tom,
The article I posted is a couple pages back so adding it here too, Error 'This web browser does not support JavaScript or scripts are being blocked' when adding a Google Workspace account (microsoft.com).
Paste this path in Regedit and press Enter. Or, manually navigate the HKEY_CURRENT_USER tree to this location:
HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BROWSER_EMULATION
You should have FEATURE_BROWSER_EMULATION. Click on it and in the window on the right locate OUTLOOK.EXE. Double click on OUTLOOK.EXE, click the Decimal radio button, and set the number to 11001 and click OK.
