推荐答案

我能够从各种互联网和MSDN文档各地的样本拼凑这个code一起。这将允许您选择一个Outlook高水平的文件夹，然后将备份所有文件夹下面。在我来说，我从未想过邮件文件夹，所以我将其排除。

I was able to piece this code together from a variety of samples around the internet and MSDN docs. This will allow you to choose an outlook high level folder and will backup all folders underneath. In my case I didn't actually want mail folders so I exclude them.

        Const BACKUP_PST_PATH As String = "C:\backup.pst"    

        Dim oFolder As Outlook.MAPIFolder = Nothing
        Dim oMailbox As Outlook.MAPIFolder = Nothing

        Dim app As New Outlook.Application()
        Dim ns As Outlook.NameSpace = app.GetNamespace("MAPI")
        Try
            //if the file doesn not exist, outlook will create it
            ns.AddStore(BACKUP_PST_PATH)
            oFolder = ns.Session.Folders.GetLast()
            oMailbox = ns.PickFolder()

         For Each f As Outlook.Folder In oMailbox.Folders
            If f.DefaultItemType <> Microsoft.Office.Interop.Outlook.OlItemType.olMailItem And f.FolderPath <> oFolder.FolderPath Then
                f.CopyTo(oFolder )
            End If
        Next

        ns.RemoveStore(oFolder)

        Catch ex As Exception
            ns.RemoveStore(oFolder)
            IO.File.Delete(BACKUP_PST_PATH)
            Throw ex
        End Try
