Defender exclusion doesn't work
Hi folks,
I'm working with Defender for Endpoint, managed through SCCM. I've attempted to set a folder exclusion for C:\test_folder\ via SCCM -> Antimalware Policies -> My Policy -> Exclusion Settings -> Excluded files and folders.
Everything appears correct; the excluded folder is visible in Windows settings and in the results of the Get-MpPreference command.
However, when I try to download the EICAR test file (Invoke-WebRequest "https://secure.eicar.org/eicar.com.txt" -OutFile test.txt), Defender immediately reacts by deleting it. I've successfully set several exclusions in the same manner before and they worked as expected, so I'm unsure if I've made a mistake or forgotten an additional step.
Could someone offer some guidance?
