Hello
Thank you for posting in Q&A forum.
- your policy may not work in the right computer, you can open cmd as administrator, and then type " gpresult /h C:\a.html ", to see if it has policy.
- this policy may not work as the same way which you think, you can use another way to delete event view too.
a bat file which deletes file longer than 90 days and using task scheduler to run this bat file every day.
bat file cmd like below:
ForFiles /p "C:\path\to\folder" /s /d -90 /c "cmd /c del /q @file"
Best regards
Yanhong
