Hello, As the amount of devices that can be in an Intune environment there is no limit. Our own tenant has more than 600 machines. When it comes to how many devices can be enrolled in Intune, it really depends on how the admin has set things up. By default, each user can usually enroll up to five devices, but it is not a hard limit. It can be adjusted to fit the needs of the organization. There’s also a handy feature called the user device limit. As an admin you can control exactly how many devices each user can enroll.
