How can we improve Microsoft Intune

Remove duplicates

Every time when you rebuild (reinstall Windows and Intune client) a corporate PC witch was already managed by Intune a duplicate computer record is added to Intune database. Now we manually removing duplicates every month. Can you automate it?

    Intune should retire devices based on Serial number & enrollment date. Move all dup. devices with older dates to a new "Retired" section?

    @Brian : There is already a feature that deletes old devices, called "Automatic device cleanup". Unfortunately, we also found it is not working like explained in the docs, and have a ticket open since few days on this...

    The stuff that you or Sergey noticed, is not a bug : every device is uniquely identified through its "device.id", not through its serial number.

    Unfortunately, there is no technical way for Intune to magically guess if a device object must be immediately deleted from the DB, after you enroll it one more time.

    For mobile devices, it is obviously difficult to "clone" such hardware. But if you are working with Windows VMs, and especially with snapshots, then you get the point that 1 serial number can represent more than 1 device from Intune device object point-of-view. Not even talking about working with snapshots, make it even more difficult to keep 1 unique Intune record.

    FYI : nearest MDM Microsoft competitor operates the same way : if you enroll several times the same device, you end up with several times the same SN in your DB. This is just a habit to modify, compared to what you are used to in on-prem AD world.

    Same problem exists for MacOS devices. A setting that auto deleted duplicate serial number devices that haven’t been active in X days would do the trick.

    Same issue really painfull and my technical director expect really more from this product so at this time for him this is not ready to be use in a production environment. Sad situation. You have an easy way to discover the machines per their serial number so do a match should not be so ******* your side during the enrollment.

    Please answer us. This request for Sergey has 2 years and since i know the product this has always be like that unfortunately.

    Regards

    We have the same issue. I raised a ticket with MS Intune support but it seems like they don't know the solution to this problem. (FYI we're not subscribed to MS Azure A.D.)

    We are having the same issue but instead we are managing iphones, same as above it seems to duplicate when you try to enroll a device which was managed before. Also Intune does sometime say the device is being deleted but it takes such a long time for intune to remove a device. Any way to force the purge or to do a sync?
