Automation Example

Before using the following automation code from a VB or Visual Basic for Applications project, make sure to create a reference to the Microsoft Outlook object library.

   Sub SynchronizeOutlookFolders()
      Dim outapp As Outlook.Application
      Dim olns As Outlook.NameSpace
      Dim MyInbox As Outlook.MAPIFolder
      Dim MyExplorer As Outlook.Explorer
      Dim MyMenu As CommandBar
      Dim MyCmd As CommandBarControl
      Set outapp = New Outlook.Application
      Set olns = outapp.GetNamespace("MAPI")
      Set MyInbox = olns.GetDefaultFolder(olFolderInbox)
      Set MyExplorer = MyInbox.GetExplorer
      ' Reference the Tools menu
      Set MyMenu = MyExplorer.CommandBars.Item("Tools")
      ' Reference the Synchronize All Folders command
      Set MyCmd = MyMenu.Controls("Synchronize").Controls("All Folders")
      ' Execute the Synchronize All Folders command
   End Sub

VBScript Example

The following example uses a custom Outlook form and VBScript to do the same thing:

1. Open a new mail message form.

2. On the Tools menu, click Forms and then click Design This Form.

3. Click the P.2 tab of the form.

4. Using the Control Toolbox, add a CommandButton control to the page.

5. On the Form menu, click View Code. Type or paste the following code

   into the Script Editor window.
      Sub CommandButton1_Click()
         Set MyExplorer = Application.ActiveExplorer
         Set MyMenu = MyExplorer.CommandBars.Item("Tools")
         Set MyCmd = MyMenu.Controls("Synchronize").Controls("All Folders")
      End Sub

6. On the Form menu, click Run This Form.

7. Click the CommandButton on the P.2 page to run the code.
