How does Exchange Server support mobile device management?

Exchange Server supports mobile device management primarily through the use of ActiveSync policies. These policies enable administrators to enforce a variety of security settings on mobile devices that access Exchange services, ensuring that corporate data remains secure and compliant with organizational standards.

ActiveSync allows for specific configurations, such as requiring PINs for device access, enforcing encryption, and remotely wiping data from lost or stolen devices. This capability is crucial for organizations that need to manage and secure sensitive information accessed on mobile devices, especially in a BYOD (Bring Your Own Device) environment.

The other methods mentioned, such as providing a dedicated mobile app for email access or using group policies for device configuration, do not specifically address the management of mobile devices in the same comprehensive manner as ActiveSync policies. Likewise, allowing full remote access to user PCs pertains more to remote desktop functionality than to mobile device management. Thus, the focus on ActiveSync highlights its critical role in maintaining device security and ensuring data protection in mobile environments.
