As someone who surveys different organizations networks day in and out, the amount of unpatched and out of date Exchange servers (and other internet facing services) I see is ridiculous. Most sysadmins don't have a tangible idea of the risk they take when they set this stuff up. At least Office 365 is patched and monitored on a regular basis and has actual security teams tasked with looking for potential exploits.
