This article describes how you can use Automation to create and to send a Microsoft Exchange message.

This article assumes that you are familiar with Visual Basic forApplications and that you can create Microsoft Access applications by using theprogramming tools that are provided with Microsoft Access. For more informationabout Visual Basic for Applications, see your version of the"Building Applications with Microsoft Access" manual.

NOTE: This article uses Microsoft Exchange, a product that must bepurchased and be installed separately. The Microsoft Exchange componentthat is included with Microsoft Windows 95 does not work with this article.
NOTE: The following code may not work properly if you have installed the Microsoft Outlook E-mail Security Update. For additional information about this update, depending on which version of Outlook you have, click the article numbers below to view the articles in the Microsoft Knowledge Base:

You can send a MAPI mail message with the SendObject method of Microsoft Access. However, you cannot attach external files or set certain message properties, such as message importance, when you use the SendObject method.

There are five main steps in sending a MAPI message through Automation:
  • Initialize and logon to the MAPI session.
  • Create a new message and add the message to the Outbox.
  • Add the recipients (To, Cc, and Bcc), and then resolve the names.
  • Set valid properties, such as text, subject, and importance.
  • Send the message.
To programmatically send a Microsoft Exchange message, follow these steps:
  1. Create a folder on drive C that is named Examples.
  2. Create a sample text file that is named Customers.txt in the Examples folder.
  3. Create a module, and then type the following line in the Declarations section if it is not already there:

    Option Explicit
  4. On the Tools menu, click References.
  5. In the References box, click to select OLE/Messaging 1.0 Object Library, and then click OK.

    NOTE: If this object library is not available in the References list, click Browse, and then search your Windows\System folder for the file Mdisp32.tlb.
  6. Type the following procedure:
     '--------------------------------------------------------------------    ' This procedure sets an object variable to the MAPI Session object    ' using the CreateObject() function. Then, it logs on to the session    ' using a predefined profile. As soon as you are logged on,    ' the procedure creates    ' a new message and adds it to the Messages collection of the Outbox    ' of the user. Then, it creates two recipients (one on the TO: line and    ' one on the CC: line) and then adds both to the Recipients collection    ' of the message. Next, it resolves the names of all recipients.    ' Then, it attaches a sample file before filling in the Subject,    ' Text, and Importance attributes of the message.    '--------------------------------------------------------------------     Sub SendMAPIMessage()        Dim MapiSession As Object        Dim MapiMessage As Object        Dim MapiRecipient As Object        Dim MapiAttachment As Object        Dim Recpt        Dim errObj As Long        Dim errMsg        On Error GoTo MAPITrap        ' Create the MAPI Session.        Set MapiSession = CreateObject("Mapi.Session")        ' Log on to the session. If the ProfileName argument is omitted,        ' Microsoft Exchange prompts you for the profile to use. If the        ' profile name is incorrect, you receive a runtime error.         MapiSession.Logon profilename:="Steven Buchanan"        ' Add a message to the Outbox.        Set MapiMessage = MapiSession.Outbox.Messages.Add        ' Add the recipients of the message. Note, each recipient must be        ' added separately to the Recipients collection of the Message        ' object.        With MapiMessage            Set MapiRecipient = MapiMessage.Recipients.Add            MapiRecipient.Name = "Nancy Davolio"            MapiRecipient.Type = mapiTo            Set MapiRecipient = MapiMessage.Recipients.Add            MapiRecipient.Name = "Andrew Fuller"            MapiRecipient.Type = mapiCc            Set MapiRecipient = MapiMessage.Recipients.Add            MapiRecipient.Name = "Michael Suyama"            MapiRecipient.Type = mapiBcc            ' Resolve each recipient's e-mail name.            ' Starting with Outlook version 8.03 (ref. Q172623)             ' OLE Messaging 1.0 was replaced with Active Messaging 1.1.            ' Outlook 98 (version 8.5) replaced Active Messaging            ' with Microsoft CDO (Collaborative Data Objects) 1.21.            ' OLE Messaging 1.0 uses a zero-based Recipients collection;            ' Active Messaging 1.1 and Microsoft CDO 1.21 are 1-based.            For Recpt = 1 To .Recipients.Count               .Recipients(Recpt).Resolve showdialog:=False            Next            ' Attach a file to the message.            Set MapiAttachment = MapiMessage.Attachments.Add            With MapiAttachment                .Name = "Customers.txt"                .Type = mapiFileData                .Source = "C:\Examples\Customers.txt"                .ReadFromFile filename:="C:\Examples\Customers.txt"                .position = 2880            End With            ' Assign the text, subject, and importance of the message.            .subject = "My Subject"            .Text = "This is the text of my message." & vbCrLf & vbCrLf            .importance = mapiHigh            ' View the message in Microsoft Exchange before sending. Set            ' the ShowDialog argument to False if you want to send the            ' message without viewing it in Microsoft Exchange.            .Send showdialog:=True        End With        Set MapiSession = Nothing  ' Clear the object variable.     MAPIExit:        Exit Sub     MAPITrap:        errObj = Err - vbObjectError  ' Strip out the OLE automation error.        Select Case errObj            Case 275                  ' User cancelled sending of message.                Resume MAPIExit            Case Else                errMsg = MsgBox("Error " & errObj & " was returned.")                Resume MAPIExit            End Select     End Sub					
  7. Make sure to replace both the Mapisession.Login Profilename and the with valid e-mail names.
  8. To test this procedure, type the following line in the Debug window, and then press ENTER:


    Note that Microsoft Exchange is invoked with the sample message ready to send.
