Occasionally my office's security group sends out fake phishing emails to make sure that everyone is able to avoid simple scams. Some are better than others and recently they've turned to more targeted spear-phishing and caught a lot of employees with their last email.
I've done well to avoid them so far but I wanted to add an extra layer of protection for myself in case I nearly fall for one in the future. So far, they've always been kind enough to send their phishing emails from an external address to mimic real attempts. These emails have a subject line like [EXTERNAL] ..." and direct you to click a link and prompt you to sign into an external portal.
My intent was to implement some vba that would trigger when a link is clicked/followed in an email which has EXTERNAL in the subject line, but I've had no luck finding any resources that follow a similar idea. I'm not even sure if it's possible, really. I've checked the events for MailItem but nothing really stands out as applicable to my needs.
Any ideas would be appreciated!
