This topic explains how to use the Exchange Management Console or the Exchange Management Shell to grant the Send As permission for a mail-enabled public folder. Use the Send As permission in Microsoft Exchange Server 2007 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 is not granted until after replication has occurred. Replication times depend on your Microsoft Exchange and network configuration.

Before You Begin

To perform this procedure, the account you use must be delegated the following:

  • Exchange Organization Administrator role

For more information about permissions, delegating roles, and the rights that are required to administer Exchange 2007, see Permission Considerations.

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 information about how to change your public folder settings, see How to View or Configure the Settings of Mail-Enabled Public Folders.

In Microsoft Office Outlook, users will receive the following errors when attempting to send a message on behalf of a mail-enabled public folder that is hidden from address lists:

  • Online mode   When users press Send, they will receive the following error: "You do not have permission to send on behalf of the specified user."

  • Cached Exchange Mode   Outlook initially sends the message, but users will receive a non-delivery report (NDR) containing the following message: "You are not allowed to send this message because you are trying to send on behalf of another user without permission to do so. Please verify that you are sending on behalf of the correct sender, or ask your system administrator to help you get the required permission"
