Windows 10: Issue removing the phantom device from Microsoft Account

Hi all,


Looking for advice on a device that has been cleared, sold, and removed from my Microsoft family account (and my daughters Microsoft account) [confirmed this by signing into my account and my daughters to remove it from both].


However, when I sign into my account, it states that my daughter needs to log onto the ‘phantom’ device using her Microsoft Account to ensure that family features work properly (phantom because it has been removed from both Microsoft accounts). The phantom device has been factory reset, renamed and sold to someone else so, this is not possible. However, I’m concerned that the family features on all remaining devices may be affected by this log-in requirement on the phantom device (as per the warning when I log into my account).


Hoping somone can tell me how to get rid of this warning message and address this issue...


Regards,

W33EES

Unknown devices on my Microsoft account


Hello Flemmingk,

Could these other devices be from friends that you may have signed in to your Microsoft account on for something?

Either way, you can remove these devices.

Afterwards to be safe, I would recommend to change the password of your Microsoft account, and enable two-step verification if you haven't already.
