Hello,

I would like to block other file attachments for Outlook via GPO.

I've created a GPO where I've added these file extensions to Layer1.

As a test I try it with only one file extension (MHT) and I have also chosen the

setting Security Form Setting for Security Mode GPO-use. GPresult shows me that

the settings arrive. Standard blockages like COM, BAT and EXE work too.

But, for example, MHT files are not blocked by Outlook.

What am I doing wrong?
