Signature update finished. No updates needed. Co-managed device

Copper Contributor

I have an issue where Security Intelligence update is being delayed by a number of days and can't figure out why.

Currently testing migrating from another AV product to Defender for Endpoint(3rd Party AV has been uninstalled) current set up is;

Device Hybrid Joined

Co-management with SCCM / Intune. SCCM handling Windows Update. Intune managing Defender. (AV, Firewall, ASR, Web Content Filtering) all this works apart from Security Intelligence updates every hour as configured in Intune! 


Signature Updates appear to wait until they are over 72hrs before updating, and I can't force the update as I get the following:

C:\Program Files\Windows Defender>MpCmdRun.exe -SignatureUpdate
Signature update started . . .
Signature update finished. No updates needed


Amended SCCM default Antimalware policy sources to WinUpdate and MMPC and to update every 1hr incase these somehow are impacting 


Can anyone help what could be causing this delay please?
