This topic no longer applies to the cloud-based service. It applies only to on-premises Exchange 2013. To see the current version of the topic that applies to the cloud-based service, change the (v=exchg.150) value in the URL to (v=exchg.160).

Use the New-SharingPolicy cmdlet to create a sharing policy to regulate how users inside your organization can share calendar and contact information with users outside the organization. Users can only share this information after federation has been configured in Exchange. After federation is configured, users can send sharing invitations that comply with a sharing policy to external recipients in other Microsoft Exchange Server 2013 and Exchange Server 2010 organizations that have federation enabled. A sharing policy needs to get assigned to a mailbox to be effective. If a mailbox doesn't have a specific sharing policy assigned, a default policy enforces the level of sharing permitted for this mailbox.

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

New-SharingPolicy -Domains <MultiValuedProperty> -Name <String> [-Confirm [<SwitchParameter>]] [-Default <SwitchParameter>] [-DomainController <Fqdn>] [-Enabled <$true | $false>] [-Organization <OrganizationIdParameter>] [-WhatIf [<SwitchParameter>]]

This example creates the sharing policy Contoso for the domain, which is a domain outside the organization. This policy allows users in the domain to see detailed free/busy information and contacts. By default, this policy is enabled.

New-SharingPolicy -Name "Contoso" -Domains ' CalendarSharingFreeBusyDetail, ContactsSharing'

This example creates a default sharing policy, which is applied to all mailboxes that don't implicitly have a sharing policy assigned to them. This sharing policy SharingPolicy01 applies to two different domains, and the sharing policy is disabled.

New-SharingPolicy -Name "SharingPolicy01" -Domains ' CalendarSharingFreeBusySimple', ' CalendarSharingFreeBusySimple' -Enabled $false -Default $true

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 "Sharing policies" entry in the Recipients Permissions topic.


Parameter Required Type Description




The Domains parameter specifies the domains to which this sharing policy applies and the sharing policy actions. Values for this parameter take the format: 'Domain: SharingPolicyAction'.

The following sharing policy action values can be used:

  • CalendarSharingFreeBusySimple   Share free/busy hours only

  • CalendarSharingFreeBusyDetail   Share free/busy hours, subject, and location

  • CalendarSharingFreeBusyReviewer   Share free/busy hours, subject, location, and the body of the message or calendar item

  • ContactsSharing   Share contacts only

Separate multiple domains with a comma, for example, ' CalendarSharingFreeBusySimple', ' CalendarSharingFreeBusyDetail, ContactsSharing'.

A domain doesn't include subdomains. You must configure each subdomain separately.




The Name parameter specifies the name of the new sharing policy.




The Confirm switch causes the command to pause processing and requires you to acknowledge what the command will do before processing continues. You don't have to specify a value with the Confirm switch.




The Default switch specifies that this sharing policy is the default sharing policy for all mailboxes. If no sharing policy has been applied to a mailbox, the default policy is automatically applied. If you want to disable sharing across your organization, you can set the default policy as disabled.

You don't have to specify a value with this switch.




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.




The Enabled parameter specifies whether to enable the new sharing policy. Valid input for this parameter is $true or $false. The default is $true.

When the sharing policy is disabled, users who are provisioned to use this policy continue to share information until the sharing policy assistant runs and removes the permissions on the shared folder. The frequency with which the sharing policy assistant runs is assigned in the Set-MailboxServer cmdlet using the SharingPolicySchedule parameter.




This parameter is reserved for internal Microsoft use.




The WhatIf switch instructs the command to simulate the actions that it would take on the object. By using the WhatIf switch, you can view what changes would occur without having to apply any of those changes. You don't have to specify a value with the WhatIf switch.
