How to Setup Automatic Intune Device Cleanup Rules

In this quick blog post, you will learn more details about how to set up Automatic Intune device cleanup rules. This cleanup task is similar to SCCM maintenance tasks.

However, you don’t have the same (like SCCM) control on Intune maintenance tasks.

NOTE! – It’s not mandatory to set the cleanup rules within your Intune tenant because of the default behavior explained below.

Automatic Device Cleanup Rules Options

These Device Cleanup rules are available to automatically remove devices that haven’t checked in for several days that you set. Go to the Intune pane, choose Devices, and select Device cleanup rules to see a new law.

NOTE 1 – You can have custom days value between 90 to 270. When you enter 89 or 269, Intune won’t allow you to save the settings.

NOTE 2 – Once you click the Save button, all devices that have been inactive for the specified number of days will immediately be deleted from Intune. Intune will continue to delete devices as they exceed the number of set days. Reports with data about the removed devices may take up to 48 hours to refresh.

When you set Delete Devices based on the last check-in Date to No, Intune automatically deletes all devices that haven’t checked in to Intune for more than 270 days.

Intune Device Cleanup Rules Behavior

Set your Intune device cleanup rules to delete Intune MDM Enrolled and Co-Managed SCCM devices that appear as any of the following conditions, then Intune applies cleanup rules immediately.

  • Inactive
  • Stale
  • Unresponsive

NOTE 1 – Intune will also make sure the device is relevant by performing this cleanup task continuously so that your device records remain current.

NOTE 2 – This deletion action won’t remove or delete or clean up the device from Azure Active Directory. More details are in the Resources section.

How to Find Out Affected Devices

Intune provides an option to find out and export the affected devices with the Device Cleanup rules you just implemented above.

Once you click the Save button on Device Cleanup Rules, all devices that have been inactive for the specified number of days (90 Days in the above example) will immediately be deleted from Intune.

NOTE! To ensure whether you are deleting the correct devices, I recommend clicking on the “View Affected Devices” link and confirming whether you want to remove those devices.

These are the devices that haven’t checked in for 90 Days.
