如何在傳送郵件時自動移除主旨行中的某些特殊字符？

Author: Xiaoyang Last Modified: 2025-08-06

在Outlook中傳送郵件時，您可能在主旨行輸入主旨時不小心插入了一些特殊字符，因此您需要逐一移除這些特殊字符。在本文中，我將介紹如何在傳送郵件時自動移除主旨中的所有這些特殊字符。

使用VBA代碼在傳送郵件時自動移除主旨行中的所有特殊字符

在傳送郵件時自動移除主旨行中的特殊字符，以下VBA代碼可以幫助您。請按照以下步驟操作：

1. 按住ALT + F11鍵以打開Microsoft Visual Basic for Applications窗口。

2. 在Microsoft Visual Basic for Applications窗口中，雙擊 Project1(VbaProject.OTM)窗格中的ThisOutlookSession以打開模組，然後複製並將以下代碼粘貼到空白模組中。

VBA代碼：自動移除主旨行中的特殊字符

Private Sub Application_ItemSend(ByVal Item As Object, Cancel As Boolean)
    Dim xMailItem As Outlook.MailItem
    Dim xRegExp As RegExp
    Dim xSubject As String
    On Error Resume Next
    If Item.Class <> olMail Then Exit Sub
    Set xMailItem = Item
    xSubject = xMailItem.Subject
    Set xRegExp = CreateObject("VBScript.RegExp")
    With xRegExp
        .Global = True
        .IgnoreCase = True
        .Pattern = "[^a-zA-Z0-9\u4e00-\u9fa5]"
    End With
    If xRegExp.test(xSubject) = False Then Exit Sub
    xSubject = xRegExp.Replace(xSubject, "-")
    xMailItem.Subject = GetTargetStr(xSubject)
    Set RegExp = Nothing
End Sub
Function GetTargetStr(Str As String)
    Dim xS, xStr As String
    Dim i As Integer
    Dim xIsFirst As Boolean
    xIsFirst = True
    xStr = ""
    For i = 1 To Len(Str)
        xS = Mid(Str, i, 1)
        If xS = "-" Then
            If xIsFirst Then
                xS = " "
                xIsFirst = False
            Else
                xS = ""
            End If
        Else
            xIsFirst = True
        End If
        xStr = xStr + xS
    Next i
    GetTargetStr = xStr
End Function

3. 然後，仍然在 Microsoft Visual Basic for Applications窗口中，點擊工具 > 引用以進入References-Project1對話框，並從可用引用列表框中勾選Microsoft VBAScript Regular Expressions 1.0選項，參見截圖：
