Use the Set-ActiveSyncDeviceAccessRule cmdlet to set the level of access for the rule.

For information about the parameter sets in the Syntax section below, see Syntax.

Set-ActiveSyncDeviceAccessRule -Identity <ActiveSyncDeviceAccessRuleIdParameter> [-AccessLevel <Allow | Block | Quarantine>] [-Confirm [<SwitchParameter>]] [-DomainController <Fqdn>] [-WhatIf [<SwitchParameter>]]

This example changes the access level granted to phones covered by the rule ContosoPhone (DeviceModel) to Quarantine.

Set-ActiveSyncDeviceAccessRule 'ContosoPhone(DeviceModel)' -AccessLevel Quarantine

This example changes the organization's device access rule so that all devices explicitly allowed to access Microsoft Exchange ActiveSync are quarantined.

Get-ActiveSyncDeviceAccessRule | Where {$_.AccessLevel -eq 'Allow'} | Set-ActiveSyncDeviceAccessRule -AccessLevel Quarantine

Your rule can define multiple groups of devices: allowed devices, blocked devices, and quarantined devices.

You need to be assigned permissions before you can run this cmdlet. Although all parameters for this cmdlet are listed in this topic, you may not have access to some parameters if they're not included in the permissions assigned to you. To see what permissions you need, see the "Exchange ActiveSync settings" entry in the Clients and mobile devices permissions topic.


Parameter Required Type Description




The Identity parameter specifies the identity of the device access rule.




The AccessLevel parameter specifies whether the devices are allowed, blocked, or quarantined.

This parameter is available only in on-premises Exchange 2013.

The DomainController parameter specifies the fully qualified domain name (FQDN) of the domain controller that writes this configuration change to Active Directory.
