set.
Allow non­provisionable devices
This ActiveSync mailbox policy controls whether pure Google devices that support some but not
all of your mailbox policies can synchronize information with your Exchange server.
If all your mailbox policies are supported (as described in this section), this policy has no effect.
If only some of your mailbox policies are supported and you set this policy, Android enforces the
supported policies when users add Exchange accounts to their devices and sync information.
If only some of your mailbox policies are supported by Android and you don’t set this policy,
users cannot add Exchange accounts to their devices. Also, any existing accounts will be
prevented from syncing information in the future (no existing information is deleted).
Allow attachment download
This policy controls whether email attachments can be downloaded to devices.
Maximum attachment size
This policy limits the maximum size of email attachments that are automatically downloaded.
Disable camera
This policy controls whether the device camera can be used. If a device has multiple users and
only one has the policy installed, the policy is applied globally. No user can use the camera in
this case.
Require device encryption
If you set this ActiveSync mailbox policy, users must secure their devices with encryption.
Emails will no longer sync if the device is not encrypted.
Only the primary user (the device owner) can encrypt the device data. If the policy is installed for
a secondary user, the owner must encrypt the device to comply with the secondary user’s
installed policy.
Require storage card encryption
If you set this policy, users must encrypt devices that don't have a separate SD card. Nexus
Galaxy, Nexus S, Nexus 4, Nexus 7, and Nexus 10 support this policy; Motorola Xoom does not.
