One of the world’s worst, most-annoying spam-prevention systems is the one in my current version of Outlook — Microsoft® Outlook® 2003 (11.8002.6568) SP2. I’d say about one out of every three times I attempt to click on a link in an email, I get a warning telling me that all links in the message have been disabled to help protect me from ones that may be “harmful”. As far as I can tell there is no way to globally deactivate this, so I have to continually enable links before I can click anything. It is obnoxious and insulting and I hate it.
