Reasons for Windows Defender Scheduled Quick Scan to stop

Question

Hi,
Does anyone have knowledge about Windows Defender Scheduled Quick Scan stopping without completing?
In our Active Directory environment, Daily Quick Scan is scheduled using MECM's Anti-malware policy.
(I believe it functions as Active Directory group policy does.)
On some of our Windows 10 client PC, the scheduled scan is not executed at all.

I would appreciate if anyone knows reasons why the scan could not be performed or canceled after it started.
Thank you,

Hi, @堀 真大
Thank you for posting in Microsoft Q&A forum.
To use MECM Anti-malware policy, first make sure that Configuration Manager is configured for Endpoint Protection:

We can monitor the quick scan status under the Monitor -> Operations in MECM console, what's the status of your?

And if we try to right click the clients, and trigger the Quick Scan manually, will it executed on clients?
