Troubleshooting the “Device Limit Reached” Error in Intune Android Enrollment

When your users try to enroll their Android devices in Microsoft Intune, they might hit a frustrating roadblock: the dreaded “Device Limit Reached” error. This message appears in the Company Portal app and stops enrollment cold, leaving users unable to access work resources. Here’s what causes this error and how to fix it quickly.

What’s Behind the Device Limit Error?

By default, Intune allows each user to enroll up to 15 devices. Once they hit this ceiling, any new enrollment attempts fail with an error message like:

“You have added the maximum number of devices allowed by your company support. Please remove a device from the Azure Portal or get help from your company support.”

The tricky part? Even old, unused devices count toward this limit until an admin manually removes them from Intune. So a user who’s upgraded phones several times or switched between work laptops may unknowingly be carrying around a collection of inactive devices that block new enrollments.

Quick Diagnosis Steps

Before diving into fixes, confirm you’re dealing with a device limit issue:

1. Check the Company Portal logs on the affected device for the specific error message.

2. Review the user’s current device count in the Intune admin center.

3. Look at enrollment failure reports to see if this is happening to multiple users.

Solution 1: Clean Up Inactive Devices

The most common fix is removing old devices that are no longer in use:

1. Go to the Microsoft Intune admin center.

2. Navigate to Devices → All Devices.

3. Search for the affected user by their User Principal Name (UPN).

4. Review their device list and identify inactive devices (look for old enrollment dates, devices that haven’t checked in recently, or hardware you know has been replaced).

5. Select the inactive devices and choose Delete to free up enrollment slots.

Solution 2: Adjust Device Limit Policies

If your users legitimately need more than the default limit, you can modify the restriction:

1. In the Intune admin center, go to Devices → Enrollment → Device limit restrictions.

2. Select the policy affecting your users.

3. Click Properties, then Edit next to Device Limit.

4. Increase the limit (maximum is 15 devices per user).

5. Save and assign the updated policy.

Solution 3: Monitor and Prevent Future Issues

Set up monitoring to catch this problem before it affects more users:

1. Navigate to Devices → Monitor → Enrollment failures.

2. Look for patterns in device limit errors.

3. Create a regular cleanup process for removing old devices.

4. Consider setting up alerts for enrollment failures.

Pro Tips for Prevention

• Regular device audits: Review enrolled devices monthly and remove unused ones.

• User education: Teach users to unenroll old devices before getting new ones.

• Clear policies: Set expectations about how many devices users can enroll.

• Automated cleanup rules: Use Intune’s device cleanup policies to automatically remove inactive devices after a set period.

When Users Still Can’t Enroll

If cleaning up devices and adjusting limits doesn’t solve the problem, check:

• Whether the user has the right licenses assigned

• If there are conditional access policies blocking enrollment

• Whether the device meets your enrollment requirements

The “Device Limit Reached” error is one of those common Intune issues that looks complicated but usually has a simple fix. Most of the time, you’re just clearing out digital clutter—old devices that should have been removed long ago. Keep your device inventory clean, and your users will have smooth enrollment experiences.
