question

There is no direct method to do this automatically.

User initiated enrollment methods are listed at https://docs.microsoft.com/en-us/mem/intune/enrollment/windows-enrollment-methods#user-self-enrollment-in-intune.

Technically, you could also use a local group policy, but that's a catch-22 as there's no easy way to configure the local group policy if the systems aren't already managed.

@andreasbright-4989 Thanks for posting in our Q&A.

For this issue, "MDM = None" means these devices are not enrolled in intune. We suggest to try to enter Azure AD account in settings > accounts > Access work or school. Then check if the MDM = intune.

For the company portal, I just can give some information. We can download the company portal from Microsoft store store free and sign in the app with work account. We can see the video in the following link as a reference.

Hi,

Thanks for reply @Jason-MSFT @LuDaiMSFT-0289

One other thing then, the users have today license = Microsoft 365 Business Standard, and we will change this to Microsoft 365 Business Premium. And since we have configured Automatic Enrollment as you can see from the image, wouldn't this cause the machines to then automatically join Intune ?

wouldn't this cause the machines to then automatically join Intune ?

No. The auto enrollment flow is only triggered at the time a system joins AAD.
