Apply a sharing policy to mailboxes

Applies to: Exchange Server 2013

Sharing policies are a part of federated sharing and enable user-established, people-to-people sharing of calendar information with different types of external users. The sharing policy that an admin applies to the user's mailbox determines what level of access a user can share and with whom. If you don't change anything, then the default sharing policy applies to all users. If you create a new sharing policy, you have to apply that policy to mailboxes before it takes effect. A sharing policy can be applied to a single user mailbox or to multiple user mailboxes simultaneously. An admin can also disable a user's sharing policy to prevent external access to calendars.

To learn more about federated sharing, see Sharing.

This example specifies that all user mailboxes in the Marketing department use the sharing policy Contoso Marketing.

Get-Mailbox -Filter "Department -eq 'Marketing'" | Set-Mailbox -SharingPolicy "Contoso Marketing"

This example returns all mailboxes that have the sharing policy Contoso applied, and it sorts the users into a table that displays only their aliases and email addresses.
