在 Outlook VBA 中更新电子邮件主题

Question

我正在尝试创建一个按钮控制的宏来更改电子邮件的主题。在this thread 之后，我设法想出了这个：

Public Sub Confidential()

Dim Item As Outlook.MailItem
Dim oInspector As Inspector
Dim strSubject As String

Set oInspector = Application.ActiveInspector
If oInspector Is Nothing Then
    Set Item = Application.ActiveExplorer.Selection.Item(1)
Else
   Set Item = oInspector.CurrentItem
End If

strSubject = Item.Subject

' Remove previous Confidential and Legally Privileged
strSubject = Replace(strSubject, "Confidential and Legally Privileged ", "")

' Prefix subject with Confidential and Legally Privileged
strSubject = "Confidential and Legally Privileged " & strSubject

' Set the message subject
Item.Subject = strSubject


Set Item = Nothing
Set oInspector = Nothing


End Sub

IF 语句是我试图涵盖的基础：当 ActiveInpector 设置时，用户可以在弹出窗口中编辑电子邮件，或者用户可以在 reading pane 中编辑它 - 当 ActiveExplorer.Selection 设置时.

问题在于，在第一种情况下，宏按预期工作，而在第二种情况下，主题没有改变（即使在调试代码时我可以看到它在改变）。如果消息被选中但未编辑（即用户尚未单击“回复”按钮），则更有趣的是，宏可以很好地更改消息列表中的主题。

现在，我找到了this thread，但是 a) 它已经超过 6 年了，b) 指向的论坛已经不存在了。正如其中所建议的，我尝试了Item.Save 方法，但它似乎没有做任何事情，除了关闭带有原始主题的编辑消息。

感谢@Ryan Wildry 的回答：如果在资源管理器窗格中编辑电子邮件，请使用.Display 方法强制弹出然后使用它：

Dim Item As Outlook.MailItem
Dim oInspector As Inspector
Set oInspector = Application.ActiveInspector

If oInspector Is Nothing Then
    Set Item = Application.ActiveExplorer.Selection.Item(1)
    Item.Display   'Force the po-up
    Set oInspector = Application.ActiveInspector  'Reassign oInpsector and Item again
    Set Item = oInspector.CurrentItem
Else
   Set Item = oInspector.CurrentItem
End If

这是你想要做的吗？

Option Explicit
Public Sub Confidential()
    Dim Item As Outlook.MailItem
    Dim oInspector As Inspector
    Dim strSubject As String
    Dim strPrefixSubject As String

    Set oInspector = Application.ActiveInspector

    If oInspector Is Nothing Then
        Set Item = Application.ActiveExplorer.Selection.Item(1)
    Else
       Set Item = oInspector.CurrentItem
    End If

    strSubject = "Confidential and Legally Privileged "

    Debug.Print Item.Subject

    ' Remove previous Confidential and Legally Privileged
    Item.Subject = Replace(Item.Subject, strSubject, "", vbTextCompare)
    Item.Save

    ' Prefix subject with Confidential and Legally Privileged
    strPrefixSubject = "Confidential and Legally Privileged " & Item.Subject

    ' Set the message subject
    Item.Subject = strPrefixSubject
    Item.Save


    Set Item = Nothing
    Set oInspector = Nothing

End Sub
