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 Microsoft Exchange Server 2010. After federation is configured, users can send sharing invitations that comply with a sharing policy to external recipients in other Exchange 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.


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

Detailed Description

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 Mailbox 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, 'mail.contoso.com: CalendarSharingFreeBusySimple', 'mail.fabrikam.com: 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 parameter 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 parameter.




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 available for multi-tenant deployments. It isn't available for on-premises deployments. For more information about multi-tenant deployments, see Multi-Tenant Support.

The Organization parameter specifies the organization in which you'll perform this action. This parameter doesn't accept wildcard characters, and you must use the exact name of the organization.




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.

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

Copy Code
New-SharingPolicy -Name "Contoso" -Domains 'mail.contoso.com: 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.

Copy Code
New-SharingPolicy -Name "SharingPolicy01" -Domains 'mail.contoso.com: CalendarSharingFreeBusySimple', 'mail.fabrikam.com: CalendarSharingFreeBusySimple' -Enabled $false -Default $true
