You’ll have to repeat the below process of each file extension you don’t want to be prompted again for. So disabling it for zip-files will not disable it for htm-files. This option cannot be disabled with standard user privileges. In that case, you’ll need to change the file opening behavior via the Registry.
However, depending on the file extension, this convenient trick may still not work.

How can I enable this checkbox and get rid of the prompt when opening my attachment? There is an option which says “Always ask before opening this type of file” which I want to turn off but I can't since it is greyed out. I would like to open it but I don't want to answer this question again. When I double click on an attachment, I’m being asked whether I would like to open or save the file.
