HI BERNIE,
changing security settings doesn't change the way outlook is set up to work, See below:
I received a message with an attachment, but I can't see or open the attachment

By default, Microsoft Outlook blocks attachment files ( such as .bat, .exe, .vbs, and .js) that can contain viruses. You cannot see or access the attachments. Your Inbox will display the paperclip icon in the Attachment column to let you know that the message has an attachment, and you will see a list of the blocked attachment files in the InfoBar at the top of your message. If you try to open the attachment by right-clicking the item, View Attachments will not appear on the shortcut menu. If you need to use files, such as .exe files, from others, have them post the files to a network share or to a Web share that you can access.
