@Abhi, Thanks for posting in Q&A.
For the setting, I notice it is for Microsoft Edge. For outlook, this is another application. So it doesn't work.
After researching the app configuration policy setting on outlook. I didn't find the setting with Azure AD single sign in on.
You can contact outlook and Azure AD support to see if there's any other method to accomplish this.
Thanks for your understanding and have a nice day!
