Sorry, no, not that I know of. Sometimes, a device can popup an alert and allow you to install the certificate it finds and thus allow you to connect. Ideally, the root certificate can be placed on a web server so that you can use the browser to find and install the certificate and then allow access to Exchange.

Is there a configuration or permissions in Exchange 2013 that will allow a mobile device (iphone, Android primarily), to connect to Exchange without a 3rd party cert or installing a cert? Autodiscovery does not work.

How can I get mobile devices to connect to Exchange 2013 without a cert?

Exchange is the server side of a collaborative application product that is part of the Microsoft Server infrastructure. Exchange's major features include email, calendaring, contacts and tasks, support for mobile and web-based access to information, and support for data storage.

Exchange

Smartphones run using a variety of operating systems -- Android, iOS and Windows Mobile most commonly -- and an even wider variety of programming languages, including Objective-C, Java, Visual C#, C++ and .NET, not to mention HTML5 and JavaScript, and cross-platform frameworks such as PhoneGap.

Smartphone Programming

The iPhone is a smartphone made by Apple Inc. It and the iPad, along with several other mobile devices from Apple, run on the iOS operating system, which has its own topic, as does the iPad for device-specific questions. Native iOS applications are written in Objective-C or in Swift using the Cocoa Touch frameworks or HTML5 compiled with the help of a package manager such as Adobe PhoneGap; a common IDE is Xcode.
