如何使用VBA根据主题和发件人名称保存Outlook电子邮件？

Question

我需要将符合以下条件的电子邮件保存在桌面文件夹中：

1. 主题以RE：FOR REVIEW开头
2. 发件人名称为：Alpha，Beta或Gamma（示例）

如果同时满足这两个条件，则会弹出“是/否”消息框。

代码：

Private WithEvents InboxItems As Outlook.Items
Sub Application_Startup()
Dim xNameSpace As Outlook.NameSpace
Set xNameSpace = Outlook.Application.Session
Set InboxItems = xNameSpace.GetDefaultFolder(olFolderInbox).Items
End Sub

Private Sub InboxItems_ItemAdd(ByVal objItem As Object)
 Dim FSO
 Dim xMailItem As Outlook.MailItem
 Dim xFilePath As String
 Dim xRegEx
 Dim xFileName As String
 Dim Output As String
 Dim Item As Object
 On Error Resume Next

  If (Item.Subject Like "RE:FOR REVIEW*") And ((Item.SenderName = "Alpha") Or (Item.SenderName = "Beta") or (Item.SenderName = "Gamma") ) Then
   Output = MsgBox("Do you want to save this email?", vbYesNo + vbQuestion, "Reminder")
   If Output = vbNo Then Exit Sub
    Else
     xFilePath = CreateObject("WScript.Shell").SpecialFolders(16)
     xFilePath = "C:\Users\ABC\Desktop\Test"
     Set FSO = CreateObject("Scripting.FileSystemObject")
     If FSO.FolderExists(xFilePath) = False Then
      FSO.CreateFolder (xFilePath)
     End If
     Set xRegEx = CreateObject("vbscript.regexp")
    xRegEx.Global = True
    xRegEx.IgnoreCase = False
    xRegEx.Pattern = "\||\/|\<|\>|""|:|\*|\\|\?"
    If objItem.Class = olMail Then
     Set xMailItem = objItem
    xFileName = xRegEx.Replace(xMailItem.Subject, "")
    xMailItem.SaveAs xFilePath & "\" & xFileName & ".html", olHTML
    End If
   End If

Exit Sub
End Sub

问题：
所有主题行和所有用户的弹出窗口都会出现。

我尝试使用嵌套的If if，但是没有得到正确的输出。

整个代码在ThisOutlookSession中。

编辑1 ，  我删除了On Error Resume Next。

修改后的代码是：

Private WithEvents InboxItems As Outlook.Items
Sub Application_Startup()
Dim xNameSpace As Outlook.NameSpace
Set xNameSpace = Outlook.Application.Session
Set InboxItems = xNameSpace.GetDefaultFolder(olFolderInbox).Items
End Sub

Private Sub InboxItems_ItemAdd(ByVal objItem As Object)
 Dim FSO
 Dim xMailItem As Outlook.MailItem
 Dim xFilePath As String
 Dim xRegEx
 Dim xFileName As String
 Dim Output As String

  If objItem.Class = olMail Then '**
  Set xMailItem = Application.CreateItem(olMailItem) '**

  If (xMailItem.Subject Like "RE:FOR REVIEW*") And ((xMailItem.SenderName = "Alpha") Or (xMailItem.SenderName = "Beta") or (xMailItem.SenderName = "Gamma") ) Then
     Output = MsgBox("Do you want to save this email?", vbYesNo + vbQuestion, "Reminder")
    If Output = vbNo Then Exit Sub
     Else
      xFilePath = CreateObject("WScript.Shell").SpecialFolders(16)
      xFilePath = "C:\Users\abc\Desktop\Test"
      Set FSO = CreateObject("Scripting.FileSystemObject")
      If FSO.FolderExists(xFilePath) = False Then
       FSO.CreateFolder (xFilePath)
      End If
      Set xRegEx = CreateObject("vbscript.regexp")
     xRegEx.Global = True
     xRegEx.IgnoreCase = False
     xRegEx.Pattern = "\||\/|\<|\>|""|:|\*|\\|\?"
     If objItem.Class = olMail Then
      Set xMailItem = objItem
     xFileName = xRegEx.Replace(xMailItem.Subject, "")
     xMailItem.SaveAs xFilePath & "\" & xFileName & ".html", olHTML
     End If
    End If
  End If
Exit Sub
End Sub

建议的If / Else结构以及适当的邮件项目。

Option Explicit

Private Sub InboxItems_ItemAdd(ByVal objItem As Object)

    Dim FSO
    Dim xMailItem As MailItem
    Dim xFilePath As String
    Dim xRegEx
    Dim xFileName As String

    If objItem.Class = olMail Then

        'objItem could be used directly but this is sometimes beneficial
        Set xMailItem = objItem

        If (xMailItem.subject Like "RE:FOR REVIEW*") Then

            If ((xMailItem.senderName = "Alpha") Or _
                (xMailItem.senderName = "Beta") Or _
                (xMailItem.senderName = "Gamma")) Then

                If MsgBox("Do you want to save this email?", vbYesNo + vbQuestion, "Reminder") = vbYes Then

                    xFilePath = "C:\Users\abc\Desktop\Test"

                    Set FSO = CreateObject("Scripting.FileSystemObject")
                    If FSO.FolderExists(xFilePath) = False Then
                        FSO.CreateFolder (xFilePath)
                    End If

                    Set xRegEx = CreateObject("vbscript.regexp")
                    xRegEx.Global = True
                    xRegEx.IgnoreCase = False
                    xRegEx.Pattern = "\||\/|\<|\>|""|:|\*|\\|\?"

                    xFileName = xRegEx.Replace(xMailItem.subject, "")

                    xMailItem.SaveAs xFilePath & "\" & xFileName & ".html", olHTML

                End If

            End If

        End If

    End If

End Sub
