I have an on-premise deployment of Windows Hello for business [Certificate Trust] using ADFS 4.0 DRS.
I also have an O365 Apps for Enterprise (Pro-plus) subscription.
The identities (users only) are synced from on-premise to Azure AD.
Only 8 attributes (Required for O365 Pro-plus is synced), [App Filtering in used]
accountEnabled
cn
displayName
objectSID
pwdLastSet
samAccountName
sourceAnchor
usageLocation
userPrincipalName
No device/group write-back is enabled, no other O365 applications are used.
I am seeing plenty of errors like ones mentioned in blog below (Q4) in Synchronization Service , where the service is trying to overwrite/remove the msds-keycredentialLink attribute [Populated to due WH4B provisoning] for insufficient permissions.

They should be triggered by the synchronization rules listed below
.
IN from AAD - User NGCKey (to DeviceKey in mv)
Out to AD – User NGCKey (from DeviceKey in mv to msds-keycredentialLink in AD)
My questions,
1. Why does it need to writeback the NGCkey ?
2. Why the errors still persists even if the below rules are disabled ?
