在资源管理器中选择项目时允许运行 Outlook VBA

Question

我有一段代码，如果我在回复某位客户时点击了 Reply 而不是 ReplyAll，则会弹出一条消息。
当我在活动窗口中打开电子邮件，但在资源管理器窗格中没有打开时，我让它运行。
我怀疑我需要在启动时运行更多的代码来设置这两种可能性。GetCurrentItem
（来自 slipstick）允许使用其中一种来获取邮件项信息，但它不会从资源管理器窗格中触发。

Dim WithEvents insp As Outlook.Inspectors
Dim WithEvents mailItem As Outlook.mailItem

' This is called on Outlook startup
Private Sub Application_Startup()
    Set insp = Application.Inspectors
End Sub

' This is called when a new Inspector is created.
Private Sub insp_NewInspector(ByVal Inspector As Inspector)
    If Inspector.CurrentItem.Class = olMail Then
       Set mailItem = Inspector.CurrentItem
    End If
End Sub

' Called when you press Reply
Private Sub mailItem_Reply(ByVal Response As Object, Cancel As Boolean)
    Dim msg As String
    Dim result As Integer
    Dim strReplyAddress As String
    Dim strtest As String
    Dim olReply As mailItem
    
    ' enter the email address of your most valued customer here
    strReplyAddress = "[email protected]" 

    Set mailItem = GetCurrentItem() ' should allow code to run in explorer or inspector

    ' this checks the reply email address.
    ' If it is the most valued customer then
    '  we need to see if Reply All has been selected!

    If mailItem.Sender.Address = strReplyAddress Then
    ' check how many recipients.
    ' If it is greater than one then it is not being sent to ALL!!

        If mailItem.Recipients.Count > 1 Then

            msg = "You are replying to Sender Only" & vbCr & vbCr & _
              "Do you want to Reply to All?" _
              & vbCr & vbCr & "Click Yes to SEND to ALL" & vbCr & vbCr & _
              "Click No to reply to SENDER ONLY" & vbCr & vbCr & _
              "Click Cancel to CANCEL THIS EMAIL"

            result = MsgBox(msg, vbYesNoCancel, "Reply Check")
            If result = vbYes Then
                Cancel = True
                Set olReply = mailItem.ReplyAll

                ' this displays the email for sending with all recipients added.
                olReply.Display 
            End If

            If result = vbCancel Then
                Cancel = True ' this stops the email from being created.
            End If

        ' by default if you click NO the code ends up here
        '  without modification and displays the email
        End If
    End If

End Sub

这就是如何触发选择改变事件。

Dim WithEvents insp As Inspectors
Dim WithEvents mailItem As mailItem

Dim WithEvents myOlExp As Explorer

' This is called on Outlook startup
Private Sub Application_Startup()
    Set insp = Inspectors
    Set myOlExp = ActiveExplorer
End Sub

Private Sub myOlExp_SelectionChange()

    ' https://docs.microsoft.com/en-us/office/vba/api/Outlook.Explorer.SelectionChange
    ' there can be an array out of bounds error when changing folders
    ' uncomment if an error occurs
    'On Error Resume Next
    Set mailItem = ActiveExplorer.Selection(1)
    'Debug.Print mailItem.subject

    ' Remove error bypass as soon as the purpose is served
    On Error GoTo 0
    
End Sub

' This is called when a new Inspector is created.
Private Sub insp_NewInspector(ByVal Inspector As Inspector)
    If Inspector.currentItem.Class = olMail Then
       Set mailItem = Inspector.currentItem
    End If
End Sub


' Called when you press Reply
Private Sub mailItem_Reply(ByVal Response As Object, Cancel As Boolean)

    Dim msg As String
    Dim result As Integer
    Dim strReplyAddress As String
    Dim strtest As String
    Dim olReply As mailItem
        
    strReplyAddress = "[email protected]" ' enter the email address of your most valued customer here
    
    ' this checks the reply email address.
    ' If it is the most valued customer then we need to see if Reply All has been selected!
    If mailItem.Sender.Address = strReplyAddress Then
    
    ' check how many recipients in Response
    '  if equal to one then not being sent to ALL!!
                
        Debug.Print Response.Recipients.count
        If Response.Recipients.count = 1 Then

            msg = "You are replying to Sender Only" & vbCr & vbCr & "Do you want to Reply to All?" _
            & vbCr & vbCr & "Click Yes to SEND to ALL" & vbCr & vbCr & _
            "Click No to reply to SENDER ONLY" & vbCr & vbCr & _
            "Click Cancel to CANCEL THIS EMAIL"

            result = MsgBox(msg, vbYesNoCancel, "Reply Check")
            If result = vbYes Then
                Cancel = True
                Set olReply = mailItem.replyall
                olReply.Display 'this displays the email for sending with all recipients added.
                
            ElseIf result = vbCancel Then
                Cancel = True ' this stops the email from being created.
                
            End If

        End If ' by default if you click NO the code ends up here without modification and displays the email

    End If
    
End Sub
