Unable to remove the Active sync devices leaf object from AD user - powershell

Question

I am trying to delete a user account from AD, but it fails as the user object contains some leaf objects (Exchange active sync devices).
Tried using the Exchange powershell cmdlet:
Remove-ActiveSyncDevice
but the "ExchangeActiveSyncDevices" leaf object does not get removed from the user object.
After entering the command Remove-ActiveSyncDevice
Is there a way to completely remove the ExchangeActiveSyncDevices from the user object in AD through exchange powershell?

Answer 1

Untested by me, but by reading the documentation, this should work:
# parameter Mailbox can use any of these user properties:
# Name
# Alias
# Distinguished name (DN)
# Canonical DN
# <domain name>\<account name>
# Email address
# GUID
# LegacyExchangeDN
# SamAccountName
# User ID or user principal name (UPN)
# get the list of devices for your user and loop through, removing them one-by-one
Get-ActiveSyncDevice -Mailbox "the.user#yourcompany.com" | ForEach-Object {
$_ | Remove-ActiveSyncDevice -WhatIf
}
Exchange 2013 or later
Get-MobileDevice -Mailbox "the.user#yourcompany.com" | ForEach-Object {
$_ | Remove-MobileDevice -WhatIf
}
When satisfied with what info is shown in the console, remove the -WhatIf switch to actually have the code remove the devices.

I've had the same problem - you need to use Get-ADObject to find the empty nodes, and then pipe to Remove-ADObject to remove them. Sorry I don't have a script to share as I used Excel and some powershell commands to:
see if the node exists
check it's empty
remove the node
This is just to confirm that Remove-MobileDevice doesn't delete the empty offending node that affected my ADMT migration.
