My Exchange server is 15 feet down the hall. When I use a normal Exchange client, the only people who can see my data in clear-text are myself and my employer (who owns the Exchange server). Anyone in-between just sees an encrypted stream. But when I use Outlook for iOS, people I&#x27;ve never met at Amazon and Microsoft can see my email.<p>I think the former situation creates a legitimate expectation of privacy. I think the latter situation does not. Which is why I use Apple Mail instead of Outlook for iOS.
