Azure AD join error 8018000a

Azure AD join error code 8018000a

Recently when attempting to perform an Azure AD Join with a Windows 10 v1511 computer I got the following error:

Something went wrong.  The device is already enrolled.  You can contact your system administrator with the error code 8018000a.


That didn’t make sense because I had recently disjoined the computer from Azure AD.  I could find no reference to the object in the Azure portal either.


A Bingoogle search yielded only one relevant result… the ConfigMgr client is installed. by Per Larsen [MVP].


I knew this wasn’t the case.  So… read the error again.  “the device is already enrolled”.  Checking Settings -> Accounts -> Work Access revealed the obvious: the computer was still being managed via OMA-DM (Intune), but associated with a different user.


Ok.  Log off, then back on as the other administrator account.

Navigate back to Work Access and sure enough, the MDM enrollment was there.  Un-enroll and bingo, Azure AD Join worked!
