Hi @ Vinod Survase,
Just wondering how long did you wait to see Outlook client after Microsoft 365 Defender deployed these two add-ins?
In my tests, it was suggested that it would take 6 hours to apply in Outlook, and the official guide states that it could take up to 12 hours to apply it in your organization.
In addition, I suggest that you could check if both add-ins have been successfully deployed in Outlook on the web.
