Mail-enable or mail-disable a public folder

Public folders are designed for shared access and provide an easy and effective way to collect, organize, and share information with other people in your workgroup or organization. Mail-enabling a public folder allows users to post to the public folder by sending an email message to it. When a public folder is mail-enabled additional settings become available for the public folder in the Exchange admin center (EAC), such as email addresses and mail quotas. In the Exchange Management Shell, before a public folder is mail-enabled, you use the Set-PublicFolder cmdlet to manage all of its settings. After the public folder is mail-enabled, you use the Set-PublicFolder and the Set-MailPublicFolder cmdlets to manage the settings.

If you want users on the Internet to send mail to a mail-enabled public folder, you need to set addition permissions using the Add-PublicFolderClientPermission cmdlet.

For additional management tasks related to managing public folders, see Public folder procedures.

What do you need to know before you begin?

• Estimated time to complete: 5 minutes

• To ensure that users on the Internet can send e-mail messages to a mail-enabled public folder, the public folder needs to have at least the CreateItems access right granted to the Anonymous account. If you want to learn how to do this, see Allow anonymous users to send email to a mail-enabled public folder later in this article.

• You need to be assigned permissions before you can perform this procedure or procedures. To see what permissions you need, see the "Public folders" entry in the Sharing and collaboration permissions topic.

• For information about keyboard shortcuts that may apply to the procedures in this topic, see Keyboard shortcuts in the Exchange admin center.

3. Navigate to the public folder you want to change.

4. Right-click on the public folder, click Properties and then select the Permissions tab.

5. Select the Anonymous account, select Create items under Write, and then click OK.

Use the Exchange Management Shell to set permissions for the Anonymous account

This example sets the CreateItems permission for the Anonymous account on the "Customer Feedback" mail-enabled public folder.

Add-PublicFolderClientPermission "\Customer Feedback" -AccessRights CreateItems -User Anonymous

For detailed syntax and parameter information, see Add-PublicFolderClientPermission.
