Mobile security settings prevent unauthorized devices from accessing and downloading information from the Microsoft Exchange Server. Administrators identify which devices are allowed to access the Microsoft Exchange Server, and then identify whether the users of those devices can download or update their email, calendar, contacts, or tasks.
Administrators can also apply security policies to devices. These policies control password length and complexity, whether devices should be locked after a period of inactivity, whether devices are required to use encryption, and whether device data should be wiped following a series of unsuccessful sign-in attempts.
