With the latest updates for Outlook, there is now a new security setting that turns off hyperlinks from the content of an email, assuming the email is within a HTML content. So, as it has been the case with Internet Explorer, there is now a line which appears on top of the email telling you about that security. So, the process is like this: you click on a link from the email and you obtain that messagebox window. This is a notification of why the hyperlink doesn't work. Then, you have to click on the top line of the email to turn them on. But, you have to do this with all the emails. This is getting anoying.
The next step would be to blank the entire content of the email and asking the user each time if he wants to read the email. Or worst, whenever you will want to startup your PC, you will be prompted with something like: "Do you really want to startup your PC? Because, if you do so, malicious users could try to hack into it and they could go in your home and steal your dog!"
Talk about that!
