+Why do weblinks in my email messages get amended?

Exchange adds a secure redirect to web links in emails automatically. Not doing so would present a privacy risk to the end user. The secure URL also allows you to navigate away from and return to OWA without re-authenticating.

If the amended link was not added, when you clicked the unsecured link, your web browser would send the original URL as part of the HTTP referrer header. The referrer header would contain your username and the subject of the message that you where viewing at the time. By adding a secure URL, no confidential data is passed in the referrer request.
The above behaviour is by design and it is not possible to turn it off for privacy and security reasons, both for the individual and the University.

You may also see text which states that MailScanner has detected a potential fraud attempt. This message is displayed because MailScanner interprets the secure URL added by Exchange as a redirected webpage and as a result raises the potential fraud risk to the user.

Again, the MailScanner behaviour is by design and has been implemented to reduce the possibility of the recipient of the email being a victim of fraud.
