When you disable a sharing policy used for defining Internet calendar publishing, users who are provisioned to use the policy won't be able to share calendar information with the Anonymous Internet domain specified in the policy. However, you can't delete the sharing policy until all the users who are provisioned to use the policy have the sharing policy setting removed from their mailboxes.

Note:
When the sharing policy is disabled, users provisioned to use the policy will continue to share information until the Sharing Policy Assistant runs. To specify how often the Sharing Policy Assistant runs, use the Set-MailboxServer cmdlet with the SharingPolicySchedule parameter.

To fully disable Internet calendar publishing, you should also disable the Microsoft Office Outlook Web App virtual directory used for calendar publishing. Doing this prohibits access to the published calendar links previously shared by your Exchange organization users with external Internet users.

To learn more about Internet calendar publishing and sharing policies, see Understanding Federated Delegation.

Step 1: Use the EMC or the Shell to disable the sharing policy for Internet calendar publishing

You need to be assigned permissions before you can perform this procedure. To see what permissions you need, see the "Sharing policies" entry in the Mailbox Permissions topic.

Use the EMC

  1. In the console tree, navigate to Organization Configuration > Mailbox.

  2. In the result pane, click the Sharing Policies tab.

  3. In the result pane, click the sharing policy you set up for Internet calendar publishing.

  4. In the action pane, under the sharing policy name, click Properties.

  5. In Properties, clear the Enable sharing policy check box, and then click OK to disable the policy.

  6. On the Sharing Policies tab, verify that the Enabled column for the sharing policy is set to False.

Use the Shell

This example disables the Internet calendar publishing sharing policy Internet.

Copy Code 
Set-SharingPolicy -Identity "Internet" -Enabled $false

For detailed syntax and parameter information, see Set-SharingPolicy.

Step 2: Use the Shell to disable the Outlook Web App virtual directory used for calendar publishing

You need to be assigned permissions before you can perform this procedure. To see what permissions you need, see the "Sharing policies" entry in the Mailbox Permissions topic.

Note:
You can't use the EMC to disable the Outlook Web App virtual directory used for calendar publishing.
