Defender for Endpoint: Failed to Enable Intune Integration

Do you get the error “Failed to enable Intune integration” when activating Defender for Endpoint or Defender for Business? You’re probably just as impatient as I am. And you just logged in to the Security Portal for the first time since the Defender for Endpoint or for Business license got assigned.

Just give it some patience (15 minutes up to 24 hours, I’ve seen it all) and try again after that.

Unfortunately the message itself doesn’t give a very helpful hint. To not waste your time unnecessarily, it’s worth keeping a cool head here. In the end a green bar finally shows up and the Defender message “Failed to enable Intune integration” disappears.

If you’re using Defender for Business, the initial wizard won’t show up a second time. So you have to activate the integration manually in Intune.

I put together a walkthrough for setting up Defender for Business with the simplified administration here: Defender for Business Onboarding / Setup | scloud
