Can’t connect device to Azure AD [Ultimate troubleshooting guide]


Microsoft allows you to connect your devices to a network using Azure AD. If you use several devices, such as laptops, computers, and mobile phones, you can “enroll” them in the program. However, some users have reported an inability to enroll devices. So in this blog, I will provide a few solutions if you can’t connect a device to Azure AD.

  • The first method to connect a device to Azure AD is to make sure you have assigned a Microsoft Intune license:
    • Go to your Admin center and open “Endpoint Manager.”
    • Then head to “Users” and select a user from the list.
    • Next, go to “Licences” and “Assignments” and ensure that “Microsoft Intune” is selected.
    • Finally, click “Save.”
    • You must assign the user a Microsoft Intune and an Active Directory Premium P2.
  • The second method to connect a device to Azure AD is to check DNS settings for a current domain you have enrolled on your Office 365 admin account:
    • Go to your Admin center and click on “Settings” then “Domains.”
    • Next, head to “DNS records” and “Add record.”
    • Enter a custom DNS record as shown here.
    • Then click “Save” to finish.
  • The third method to connect a device to Azure AD is to change the user’s primary email address:
    • Open your Admin center and click on “Users” and “Active users.”
    • Select a user from the list and click on “Account.”
    • Then click on “Manage username and email.”
  • The fourth method to connect a device to Azure AD is to remove conflicting antivirus software that could prevent your program from enrolling a device onto Azure AD:
    • Type “control panel” into your Windows search bar and open your Control Panel.
    • Click on “Uninstall a program” under “Programs.”
    • Find any antivirus programs that you don’t need and uninstall them.
    • You can try Microsoft Defender instead.

I have tested each solution to ensure they work and have given you the results required to fix the issue. I suggest you go through each suggestion to learn how to resolve the problem of not being able to enroll devices onto Microsoft Azure AD.

How to check and see if you have assigned a Microsoft Intune license to a user

If you encounter an issue, such as not being able to enroll devices, you may assume that there could be a serious problem that you may not have even fixed. However, a simple solution to help fix this issue is to check and ensure that you have enrolled a user in Microsoft Intune. Devices assigned to users by your network must have an active Microsoft premium account with an Intune license.
