Greyed out "Always ask before opening this type of file"

[Guest]

For all normal workstation users (with no admin rights), anytime an
attachment is opened, you get an option to either open, save or cancel. Right
underneath these options, there is a checkbox with "Always ask before opening
this type of file."

The problem is that this checkbox is greyed out for all normal users.

Does anyone know how I can ungrey this?

After doing some research, some people were unchecking the option within the
file types to "confirm open after download" but what this will do is open the
right away when clicking on an attachment.

This would be a OS related issue not a outlook issue.
And would vary depending on what OS and what user permissions are in force
It be better to pose this question in the forum for the proper OS
