    Configuring Security Settings for Mobile Devices


    You can specify security options for your users who connect to Exchange Server by using mobile devices. With the Exchange System Manager, you can set the length and the strength of the password, the amount of inactivity time, and the number of failed attempts that can occur before the mobile device is wiped.

    For more information about setting security policies, see "Best Practice: Determine and Deploy a Device Password Policy" in Best Practices for Deploying a Mobile Messaging Solution.



    Note:

    The term password that is referenced in this topic refers to the password that a user enters to unlock his or her mobile device. It is not the same as a network user password.



    Note:

    The Wipe device after failed option is off by default.

    The following table presents the options you can use to set your security policies.

    Security Option

    Description

    Minimum password length (characters)

    Use this option to specify the required length of the user's password for his or her mobile device. The default setting is 4 characters. You can specify a password length of 4 to 18 characters.

    Require both numbers and letters

    Use this option if you want to require that users choose a password that contains both numbers and letters. This option is not selected by default.

    Inactivity time (minutes)

    Use this option to specify whether your users must log on to their mobile devices after a specified number of minutes of inactivity. This option is not selected by default. If selected, the default setting is 5 minutes.

    Wipe device after failed (attempts)

    Use this option to specify whether you want the device memory wiped after multiple failed logon attempts. This option is not selected by default. If selected, the default setting is 8 attempts.

    Refresh settings on the device (hours)

    Use this option to specify how often you want to send a provision request to mobile devices. This option is not selected by default. If selected, the default setting is every 24 hours.

    Allow access to devices that do not fully support password settings

    Select this option if you want to allow mobile devices that do not fully support the device security settings to be able to synchronize with Exchange. This option is not selected by default.

    Note:

    If the Allow access to devices that do not fully support password settings option is not selected, users that use mobile devices that do not fully support device security settings (for example, devices that do not support provisioning) will receive a 403 error message when they attempt to synchronize their mobile devices with Exchange.
