XCON: Public Folder Name Does Not Appear in the From Field When You Send a Message So That It Appears to Come from a Public Folder Address

SYMPTOMS

When you send an e-mail message to a different organization by using the Send As permission, and you specify a public folder address in the From field of that message, the message recipient sees your e-mail address in the From field of the message. You expect to see the public folder address in the From field of the message.

Note You do not experience this behavior when you use the Send As permission and specify a mailbox in the From field of the e-mail message.

CAUSE

This behavior occurs when you send the message to the other organization through an X.400 connector. When you send the message through an X.400 connector, the following information appears in the Bf0.log file of the source connector:

P1 sender = alias
P2 sender = foldername

In this information, alias is your alias, and foldername is the name of the public folder that you specified in the From field of the message. The P1 address appears in the From field of the message when the recipient receives it.

This behavior does not occur if you send the message through a Simple Mail Transfer Protocol (SMTP) connector.

WORKAROUND

To work around this behavior, create a common mailbox, and then assign other users the Send As permission to that common mailbox. Send the message by specifying the common mailbox address in the From field of the message.

MORE INFORMATION

When you double-click a mailbox in Microsoft Exchange Administrator to open the mailboxname Properties dialog box, you may notice the following:

• When you click the Delivery Options tab, you click Help, and then you click Give Send On Behalf Of Permission To, you receive the following message:

  Choose Modify to change the list of users who can send mail on behalf of this mailbox user. When mail is sent using this option, the message indicates that it was sent on behalf of another mailbox user.
  
  Note
  
  Send On Behalf Of permission differs from Send As permission, which does not indicate the actual sender. Use the Permissions property page to give Send As permission.

• When you click the Permissions tab, you click Help, and then you click Rights, you receive the following Send As permission message:

  Send messages as this mailbox. This is different from Send On Behalf Of permission because the person receiving the message cannot tell that the message has been sent by someone else. You delegate Send On Behalf Of permission using the Delivery Options property page.

This information may appear to contradict the description of the behavior in the "Symptoms" section of this article. However, this information refers to mailbox behavior and not to public folder behavior. A mailbox can use the Send As permission or the Send On Behalf Of permission so that a message appears to come from another mailbox or public folder, but a public folder cannot. The only available option for a public folder is the Send As permission. However, when you send the message through an X.400 connector, and you use the Send As permission for a public folder, the Send As permission produces the same behavior that the Send On Behalf Of permission produces when you use it for a mailbox.

Note This behavior is changed in Microsoft Exchange 2000 Server. When you use the Send As permission to make a message appear to be from a public folder address, and you send that message through an X.400 connector, the recipient sees the public folder address in the From field of that message.
