Recently, I have an e-mail message from a trusted source. Microsoft blocker appeared indicating the attachment was blocked due to harm to my computer. Later, I looked under tools on the menu button and scrolled down to internet options. On the menu under "content", I added the e-mail address as a safe sender. Next I checked my junk e-mail file to see if the e-mail and attachment was stored in junk mail. I later clicked on "options" under more options and clicked on "filtering". There was no button to unblock e-mail attachments. I have not yet found a solution for unblocking an attachment. What is the solution to this problem?
