Windows 11 File Picker UI triggers quarantine - how to disable?

Iron Contributor

Hi everyone,


we face the following problem after updating some user pcs to win 11:

When people try to share files from file explorer, windows automatically looks up contacts somehow using windows mail instead of outlook. In our domain only outlook is allowed to connect to office 365.


After the first use of share a service called "file picker UI" tries opens each restart and triggers quarantine.

Any advice anybdy?
