This blog will show you a possible method to make sure that your existing Azure Ad / Entra Joined devices and not yet MDM / Intune enrolled, are going to be automatically enrolled into Intune.
I will divide this blog into multiple parts
1. Introduction
A lot of customers will start their cloud journey by making use of Azure Ad as their Identity Provider. Most of the time, Intune wasn’t yet part of that journey. But what if you want to make sure your devices are being managed and the devices are already enrolled into Azure/Entra but not into Intune?
Today I spent some time enrolling existing Azure Ad joined /Entra devices into Intune. These devices were Azure Ad joined but without MDM/Intune enabled or configured.
This company started off with only Microsoft 365 Business standard licenses. With this particular license, we will not have the possibility to enroll the devices into Intune.
So without the possibility to enroll devices into Intune, all of the devices were only Azure Ad Joined/ Entra joined. How are we going to make sure we can enroll those Entra joined-only devices into Intune?
When you want to enroll your existing Azure Ad joined device into Intune, there are multiple options available to make sure the device will be enrolled into MDM/Intune.
Microsoft is telling us, that the official supported method is using a provisioning package.
I guess, there should be an easier way to do so? Before I am going to show you, the easy way, let’s take a look at the requirements first.
2. The Requirements
The first one is not necessarily a requirement but could make your life a lot easier. When we have a third-party remote management (RMM) tool installed on those devices, we will probably have the possibility to deploy some PowerShell script to those devices in system context. (at least our RMM tool has that option)
The system permissions are necessary because when enrolling an existing Azure Ad Joined device into Intune there is 1 major requirement. You will need to have the right privileges (local administrator) to perform that operation! Otherwise, you will end up with some nice errors.
If the permissions aren’t going to be an issue we still need to check out some other settings. To make sure users could enroll their device we need to configure the MDM scope in Intune. As shown below we made sure only users with a proper license (Business Premium) could enroll their device into MDM.
Please note: Before enrolling the device, also make sure there are no enrollment restrictions(Block Personal Devices) configured!
3. Triggering the Enrollment
When you don’t want to go through all the steps to create a provisioning package and end up as a grumpy old man we need to come up with a faster solution
If you aren’t deploying this script below with system context (RMM tool requirement) we need to download and use PSExec. (Sysinternal tools)
With Psexec -s we can start the enrollment that triggers the DeviceEnroller command with these arguments /c /AutoEnrollMDM in the System context (PSEXEC).
If you don’t execute this command in the system context you will notice a nice error mentioning: “Auto MDM ENroll: Device Credential (0x0), Failed (Access is denied). So please….use PSEXEC to kick off the enrollment if you are doing this on your own and not using an RMM tool.
Let’s continue with the script! As shown below, I am also making sure the MdmEnrollmentUrls are configured before we start the enrollment!
I got 2 PowerShell scripts.. one just doing its job and one with try/if/catch in it to make sure it catches the error it could run into
The simple one
# Set MDM Enrollment URL's
$key = 'SYSTEM\CurrentControlSet\Control\CloudDomainJoin\TenantInfo\*'
$keyinfo = Get-Item "HKLM:\$key"
$url = $keyinfo.name
$url = $url.Split("\")[-1]
$path = "HKLM:\SYSTEM\CurrentControlSet\Control\CloudDomainJoin\TenantInfo\$url"
New-ItemProperty -LiteralPath $path -Name 'MdmEnrollmentUrl' -Value 'https://enrollment.manage.microsoft.com/enrollmentserver/discovery.svc' -PropertyType String -Force -ea SilentlyContinue;
New-ItemProperty -LiteralPath $path -Name 'MdmTermsOfUseUrl' -Value 'https://portal.manage.microsoft.com/TermsofUse.aspx' -PropertyType String -Force -ea SilentlyContinue;
New-ItemProperty -LiteralPath $path -Name 'MdmComplianceUrl' -Value 'https://portal.manage.microsoft.com/?portalAction=Compliance' -PropertyType String -Force -ea SilentlyContinue;
# Trigger AutoEnroll
C:\Windows\system32\deviceenroller.exe /c /AutoEnrollMDMThe Improved One
# Set MDM Enrollment URL's
$key = 'SYSTEM\CurrentControlSet\Control\CloudDomainJoin\TenantInfo\*'
try{
$keyinfo = Get-Item "HKLM:\$key"
}
catch{
Write-Host "Tenant ID is not found!"
exit 1001
}
$url = $keyinfo.name
$url = $url.Split("\")[-1]
$path = "HKLM:\SYSTEM\CurrentControlSet\Control\CloudDomainJoin\TenantInfo\$url"
if(!(Test-Path $path)){
Write-Host "KEY $path not found!"
exit 1001
}else{
try{
Get-ItemProperty $path -Name MdmEnrollmentUrl
}
catch{
Write_Host "MDM Enrollment registry keys not found. Registering now..."
New-ItemProperty -LiteralPath $path -Name 'MdmEnrollmentUrl' -Value 'https://enrollment.manage.microsoft.com/enrollmentserver/discovery.svc' -PropertyType String -Force -ea SilentlyContinue;
New-ItemProperty -LiteralPath $path -Name 'MdmTermsOfUseUrl' -Value 'https://portal.manage.microsoft.com/TermsofUse.aspx' -PropertyType String -Force -ea SilentlyContinue;
New-ItemProperty -LiteralPath $path -Name 'MdmComplianceUrl' -Value 'https://portal.manage.microsoft.com/?portalAction=Compliance' -PropertyType String -Force -ea SilentlyContinue;
}
finally{
# Trigger AutoEnroll with the deviceenroller
try{
C:\Windows\system32\deviceenroller.exe /c /AutoEnrollMDM
Write-Host "Device is ready for Autopilot enrollment now!"
exit 0
}
catch{
Write-Host "Something went wrong (C:\Windows\system32\deviceenroller.exe)"
exit 1001
}
}
}
exit 0
4. Results:
When kicking off the PowerShell script you will need to give it some time because sometimes it could take a bit longer before the device will be enrolled into Intune successfully. In the meantime, you could notice the error Auto MDM Enroll: Failed 0x8018002b (event 76) popping up in the DeviceManagement-Enterprise-Diagnostic event log.
After some time of waiting you will notice event 75 with the message that Auto MDM Enroll: Succeeded
For the people who don’t believe that this process will only take a few seconds, here you go
5. Troubleshooting the Enrollment
I removed this part from this blog because it was becoming too large and while becoming too large it was overshadowing the main part of the blog.
Please visit this blog if you are dealing with Intune Enrollment Errors or if you are missing the scheduled task to start the enrollment

Conclusion:
When your devices are already enrolled in Azure Ad, it doesn’t mean you will need to reinstall the devices to make sure those devices are enrolled into Intune/MDM. Sometimes enrolling a device into Intune sounds easier than it is… hopefully, the troubleshooting part showed you how to deal with those kinds of situations!
Please Note: Wiping the device and enrolling it with Autopilot is the path you will need to take… but sometimes that path isn’t always available!
Hi,
thanks for your tutorial!
Do you mean Azure AD joined or registered?

best regards

how long does it take for the scheduled task to show up? How long on avg before it enrolls with Azure AD? Been waiting 4hrs and nothing on ether front. Running version 20H2
Normally, when you configure this setting your already azure ad joined device will register itself in Intune. This setting will not join the device to azure.
Thank you! I couldn’t find any mention of this on the setup or troubleshooting pages, unless I’d glazed over it.
As soon as I set this GPO and triggered the scheduled task, the devices checked in to Intune as ‘Co-managed’. Also gave them a reboot to speed up the client, rather than waiting 240 minutes for the retry.
Rudy, you are the man! This post saved me so much time and so many headaches.
Many thanks!
On a computer that is currently Azure AD Joined if you put in place the registry key in this location: HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\CurrentVersion\MDM
The device will never create the scheduled task. As soon as I made the changed via Local Group Policy Editor the scheduled task gets made as soon as I run GPUpdate. Without the local GPEDIT not even the “EnterpriseMgmt” folder within scheduled task gets generated.
Any thoughts on how to get around this so the change can be made with just a regedit? It would be a lifesaver for automating this,
Replying to myself here. I may have found a PowerShell script to do this. The scheduled task has to be made. You can’t just flip the registry keys. I’ve not tested yet but here is a potential solution: https://timmyit.com/2018/12/17/mdm-join-an-already-azure-ad-joined-windows-10-pcs-to-intune-with-a-provisioning-package/
What happens when you use C:\Windows\System32\deviceenroller.exe /c /AutoEnrollMDM from a system shell(psexec)
How would you deploy the powershell script when the devices are not managed or domain joined?
Thats going to be difficult…we used the rmm tool we deployed earlier to do so
Hey Rudy
If users enrol as local admin… Will they keep local admin on the enrolled device?
If so that seems like a big no no :o)
Regards from Denmark
Depends on what”you” configured in Intune 🙂 , as you are enrolling a device into a mdm… so I assume you have your configuration profiles in place to make sure the user isn’t going to be an admin right?
Thanks for the quick response. And All your blogs.
I end up with error “Auto MDM Enroll: Device Credential (0x0), Failed (Unknown Win32 Error code: 0x80180026)”
Any idea ?
Using psexec -i -s powershell.exe
I had an issue with your powershell, for some reason the JoinInfo and TennantInfo in the registry wasn’t there. I think I didn’t wait long enough but I’m sure what actually populates that info.
Is there any way to automatically enroll a not Azure Ad joined device to MDM only with a username/password combination? E.g., to run some scripts with an embedded username/password and MDM server enrollment URL.
Rudy! You’re an awesome bro! I used your powershell script but the scheduled task never scheduled. I still successfully enrolled my AzureAD only clients in Intune within seconds using your Psexec method. Let’s go have a beer sometime on me 🙂
In many PCs don’t have enrollment task.
After Option 3. PowerShell had error: “Reg key alredy exist.”
Then gpupdate /force – Windows failed to apply the MDM Policy settings.
How can fix this?
Found an easier way enroll Azure AD Joined devices in Intune. I ran this as the logged in user who was a local admin rights, but it might not be a requirement.
Go to Accounts > Access work or school > Enroll only in device management. Sign in using your work Microsoft credentials. Follow the bouncing ball. Done!
The device gets registered in Intune as a personal device, which you can change in Properties to Corporate if you want.
On the users device, it now shows connected to two Work accounts, one says “Connected to Contoso’s Azure AD” (this was when it was originally Azure AD Joined), and another that says Connected to Contoso for Mobile Device Management Only.
Hi… Never said that, this option wasnt possible 😛 (admin is required)
https://call4cloud.nl/2022/09/intune-the-legend-of-the-certificate/
But maybe not the best option…. as the certificate (mdm) could be stored in the user store
Hello, I stumbled across this method as well. Only thing is my user profile is not there to log into, test.user@domain.com, the PC logs straight back into the Local admin account. Any ideas to get this test.user back?
Can I just say thank you so much for this tutorial. I have wasted so much time on this and Microsoft’s documentation on this very subject sucks. It sucks like most of their documentation to be honest.
This has managed to get the devices from Azure AD to Intune. Thanks again!!
I combined both scripts and was able to enroll the computers almost instantly. Hope this helps others!

Thanks… made me realize I needed to update the script in that blogpost with the one we are always using these days 🙂
That combined script is the jam – works like a charm.. Thank you.
