如何在 Outlook 中為多個電子郵件帳戶設定不同簽名，以便在回覆或轉寄郵件時自動套用？

根據教學：Outlook 中的電子郵件簽名，您應已掌握如何在 Outlook 中建立簽名。然而，建立新簽名後，若要在回覆或轉寄郵件時使用該簽名，必須手動選取簽名已建立的簽名。

當然，您也可以透過點選簽名 > 簽名，為特定電子郵件帳戶設定簽名，讓 Outlook 在回覆或轉寄郵件時自動加入簽名（如下圖所示）。

然而，若您擁有許多電子郵件帳戶，並希望批次為多個帳戶設定不同簽名，該怎麼辦？本教學將介紹一種 VBA 方法，協助您輕鬆完成這項工作。

在 Outlook 中回覆或轉寄時為多個電子郵件帳戶設定不同簽名

1. 在 Outlook 中，按下 Alt+F11 鍵，即可開啟 Microsoft Visual Basic for Applications 視窗！

2. 在 Microsoft Visual Basic for Applications 視窗中，於專案窗格雙擊 ThisOutlookSession，並將下方 VBA 程式碼貼上至 ThisOutlookSession （程式碼） 視窗中。請參閱截圖：

VBA 程式碼：在 Outlook 中建立新建郵件時為多個電子郵件帳戶設定不同簽名 —— ThisOutlookSession

Public WithEvents GInspectors As Inspectors
Public WithEvents GExplorer As Explorer

Private Sub Application_Startup()
  Set GInspectors = Application.Inspectors
  Set GExplorer = Application.ActiveExplorer
End Sub

Private Sub GExplorer_InlineResponse(ByVal Item As Object)
‘Update by ExtendOffice
Dim xMail As MailItem
On Error Resume Next
EndTimer
If Item.Class = olMail Then
  Set xMail = Item
  Set GInspector = Nothing
  Set GInspector = xMail.GetInspector
  StartTimer
End If
End Sub

Private Sub GInspectors_NewInspector(ByVal Inspector As Inspector)
  On Error Resume Next
  EndTimer
  Set GInspector = Nothing
  Set GInspector = Inspector
  StartTimer
End Sub

3. 在 Microsoft Visual Basic for Applications 視窗中，點選插入 > 模組，然後將下列 VBA 程式碼複製到模組視窗中。

Public Declare PtrSafe Function SetTimer Lib "user32" (ByVal HWnd As Long, ByVal nIDEvent As Long, ByVal uElapse As Long, ByVal lpTimerFunc As LongPtr) As Long
Public Declare PtrSafe Function KillTimer Lib "user32" (ByVal HWnd As Long, ByVal nIDEvent As Long) As Long
Public TimerID As Long
Public GInspector As Inspector

Sub StartTimer()
  On Error Resume Next
  TimerID = SetTimer(0&, 0&, 1000&, AddressOf TimerProc)
End Sub

Sub EndTimer()
  On Error Resume Next
  KillTimer 0&, TimerID
End Sub

Sub TimerProc(ByVal HWnd As Long, ByVal uMsg As Long, ByVal nIDEvent As Long, ByVal dwTimer As Long)
  On Error Resume Next
  Call SetSignatureToAccount
  EndTimer
End Sub

    Else
      xIsNew = True
      Exit Sub
    End If

    If VBA.InStr(xSubject, "RE: ") Then
      xSignatureFile = xSignaturePath & "Signature3.htm" 'Replace "Signature3" with your actual signature name that you will set as the signature when you reply to a message.
    ElseIf VBA.InStr(xSubject, "FW: ") Then
      xSignatureFile = xSignaturePath & "Signature4.htm" 'Replace "Signature4" with your actual signature name that you will set as the signature when you forward a message.
    Else
      xIsNew = True
      Exit Sub
    End If
  'Add more Cases for more email accounts
End Select
If xIsNew = True Then
  With xDoc.Application.Selection
    .WholeStory
    .EndKey
    .InsertParagraphAfter
    .MoveDown Unit:=wdLine, Count:=1
    .InsertFile FileName:=xSignatureFile, Link:=False, Attachment:=False
  End With
