Use the Send As permission to configure a mail-enabled public folder so that users other than the public folder owner can use that mail-enabled public folder to send messages.

The Send As permission isn't granted until after replication has occurred. Replication times depend on your Exchange and network configuration. To grant the permission immediately, stop and then restart the Microsoft Exchange Information Store service.

Also, before you perform this procedure, be aware that you cannot send e-mail messages on behalf of a mail-enabled public folder if the folder is hidden from address lists. When sending a message, Exchange requires that an e-mail address is resolved in the From field. In the case where a message is sent on behalf of a mail-enabled public folder that is hidden from address lists, , the SMTP address is interpreted as an address that is not from your organization (known as a foreign address) and is rejected. For more information about how to change public folder settings, see Configure Public Folder Properties.

In Outlook, users will receive the following errors when attempting to send a message on behalf of a mailbox that is hidden from address lists:

Use the Shell to manage Send As permissions for a mail-enabled public folder

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

Use the Add-ADPermission cmdlet to manage Send As permissions for a mail-enabled public folder. When you use the Add-ADPermission cmdlet, you must specify the name of the public folder on which the Send As permission should be added and the public folder that should be granted the permission. Because the Add-ADPermission cmdlet controls many permissions, you must also specify the Send As permission with the ExtendedRights parameter. For example, to add the Send As permission to contoso\kim on the public folder Sales, use the following command:

Copy Code
Add-ADPermission Sales -User contoso\kim -Extendedrights "Send As"
