Device enrollment failing

psshutdown 1 Reputation point

I have configured Intune and testing Windows 10 device enrolment and the device is not enrolling to Intune, here is my setup:

  • Devices are Hybrid Azure AD Joined (I can confirm this by running dsregcmd /status)
  • Configured Automatic Enrolment MDM Scope to 'All' in Endpoint Manager
  • created GPO and 'enabled automatic MDM enrollment' - 'User Credentials' setting selected
  • Windows 10 version is 20H2


  • Local domain name - domain the devices are joined
  • External domain (verified in Azure)
  • User UPN is using (joe.bloggs@jaswant .com)


  • EMS+E3

The following errors appear in the Event log 'Microsoft-Windows-DeviceManagement-Enterprise-Diagnostics-Provider/Admin'

Event ID 201 - MDM Session: OMA-DM message failed to be sent. Result: (Unknown Win32 Error code: 0x80072f78).

Event ID 208 - MDM Session: OMA-DM session started for EnrollmentID (977F4BA8-B3BE-4EBF-9734-015B0FBFBD77) with server: (MS DM Server), Server version: (NULL), Client Version: (1.2), Origin: (0x26), Initiator: (0x0), Mode: (0x2), SessionID: (0x1D), Authentication Type: (0x3).

Event ID 209 - MDM Session: OMA-DM session ended with status: (Unknown Win32 Error code: 0x80072f78).

The device Sync status is: The sync could not be initiated ()x80072f78)

I have spent substial amount of time on this issue now and none of the devices are enrolling i would appreciate any help.

    0x80072f78 is a general error that indicates the server response cannot be parsed. To find the root cause, we need more logs to analyze. It is highly suggested to create a free online support ticket to resolve this issue more effectively. Here is the link:
