Other Intune-related topics, including unsupported scenarios and platform-specific behaviors
@Celeste, Thanks for posting in Q&A.
Based as I know, if the enrolled DEM account has been deleted and removed licenses, the enrolled devices may have issue to receive policy from Intune. If the user leave the company, I suggest re-enroll these devices. Or you can consider resetting the password of the account instead of removing it.
Hope the above information can help.
