Resolve 401 and 403 errors in Endpoint Manager (Intune)

Are you constantly getting 401 and 403 errors in Microsoft Intune (Endpoint Manager) while trying to set it up?

All this, despite you being a global administrator for your domain?

After a while of searching for the answer, trying to set up MDM and starting to wonder if I'd need that Azure AD Premium license after all, I found the relevant article on the Microsoft documentation pages:

https://docs.microsoft.com/en-US/microsoft-365/admin/basic-mobility-security/set-up?view=o365-worldwide

In short, you're going to have to activate "Basic Mobility and Security" before you can start your configuration. You can find the activation page here:

https://admin.microsoft.com/EAdmin/Device/IntuneInventory.aspx

Once there, click the button to enable and wait for a while. On our test tenant with ~5 accounts this took less than a minute, but on larger tenants it might take a bit longer to activate. Some reports say it might take up to a couple of hours.
