Blocking file uploads to all sites, unless safelisted
I'm going to duplicate your policy and blocked domains to see what my test results in.
The MDE status is because you're managing it with Intune versus using Microsoft Defender for Endpoint Security Configuration Management.
miller34mike, it WORKED. It finally WORKED. Thanks a mill for your help.
- which websites did the file blocking work? i tried dropbox and it did not work
Brandon_Tuck Its not resolved like still files are getting uploaded on few site i.e chatgpt and other
How did you solve this issue? I'm having the exact same problem, exact same policy made and for some reason blocking the file upload isn't working.
Thanks!
Happy to hear it is working for you! Glad I could help. Just finished building the policy too, will still give it a test. Thanks for running through all of this with me!
Btw, if you block Chrome or Firefox from handling sensitive data (endpoint DLP settings) the Microsoft Purview Extension will override that block BUT specific blocks like this should still work.
