Issue Description :

We were facing MDM errors when Outlook or any Office desktop app was activated by end user on a new Machine.

Error : CAA50024, Error response came from MDM terms of use page.

This wasn’t impacting registration of devices in Azure AD but causing annoyance to end users. I did couple of testing and it shows that users who weren’t assigned Intune licenses were getting this error when Azure AD tried to enroll devices in Intune.

Reason :

Intune license wasn’t assigned to everyone and MDM Scope was set to All. This error occurred when devices were trying to be auto-registered in Intune but lack of licenses on those users caused this issue.

Fix :

There are two type of fixes but first one is recommended :

  • Scope MDM Policy to pilot users, so they are only allowed to register device in Intune.

OR

  • Create CNAME Records, It is not recommended if you are using Intune. There isn’t any official answer but forums says that these cname should be deleted when intune is used.
