Outlook, what a joke

Even if using Exchange server, you can access email via POP or IMAP with dozens of vastly superior and more secure email clients than Outlook, which run on Linux, Mac OS and even Windows. If that the only justification you can came up with for sticking with Windows in a business environment, salvation is at hand, you will be able to ditch Vista and XP, and then perhaps save yourself the heart attack you are rapidly building yourself up to.
