AMA: Cloud-connected endpoints with Microsoft Endpoint Manager

heruy ejigu, Thanks for the question! Take a look at this doc on managing stale objects in Azure AD: https://docs.microsoft.com/en-us/azure/active-directory/devices/manage-stale-devices. There really isn't a database you can manage in AAD. Additionally, if you use PowerShell, you can manage objects using the Remove-ADComputer CMD-LET https://docs.microsoft.com/en-us/powershell/module/activedirectory/remove-adcomputer?view=windowsserver2019-ps
