OL2000: How to Programmatically Set a Form's From Field

ID: Q232309

The information in this article applies to:

Microsoft Outlook 2000

SUMMARY

You cannot directly change an item's From field using any programming methods in Microsoft Exchange or Outlook. If you could, mail could be sent on someone else's behalf without their permission, therefore the From field is read-only.

You can use the SentOnBehalfOfName property to set the From field, provided that you were given delegate permissions to send mail on someone else's behalf.

You can use the Microsoft Outlook object model to populate various fields on a form. When you create a mail message (MailItem) form to send to someone, the To, Cc, and Bcc fields are set by using the Recipients collection.

The following sample code demonstrates how to create a new mail message and populate the CC: line.

NOTE: These code examples illustrate using Automation from another program. Be sure to set a reference to the Microsoft Outlook 9.0 Object Library before running this code.


Sub TestFrom()

   Dim myOlApp as Outlook.Application
   Dim myItem as Outlook.MailItem

   ' Create an Outlook application object
   Set myOlApp = New Outlook.Application

   ' Creates a new MailItem form
   Set myItem = myOlApp.CreateItem(olMailItem)

   ' Add Jon Grande to the Recipients collection
   Set myRecipient = myItem.Recipients.Add("Jon Grande")

   ' Set the CC field to the Recipients collection defined above
   myRecipient.Type = olCC

   ' Display the item
   myItem.Display

End Sub

You can use the constants olTo, olCC, and olBCC to set the To, Cc, and Bbc address fields of the MailItem. However, olOriginator does not set the From field.

To set the From field, use the SentOnBehalfOfName property of the Item object. The following example demonstrates the use of the SentOnBehalfOfName property:


Sub TestSentOnBehalfOfName()

   Dim myOlApp as Outlook.Application
   Dim myItem as Outlook.MailItem

   ' Create an Outlook application object
   Set myOlApp = New Outlook.Application

   ' Creates a new MailItem form
   Set myItem = myOlApp.CreateItem(olMailItem)

   ' Set the "From" field
   myItem.SentOnBehalfOfName = "Jon Grande"

   ' Display the item
   myItem.Display

End Sub
