VBA宏可打开最后一封电子邮件并进行回复

Question

我有一个用于引用的excel电子表格。

电子表格具有一个宏，该宏将报价建议保存为PDF，并将其附加到新的Outlook电子邮件中。电子邮件将自动填充有报价接收者的电子邮件地址（基于excel电子表格中的电子邮件）。

我想更新代码，以便它搜索并回复从该人发送或接收的最后一封电子邮件，而不是发送全新的电子邮件。

Sub Saveaspdfandsend()
Dim xSht As Worksheet
Dim xFileDlg As FileDialog
Dim xFolder As String
Dim xYesorNo As Integer
Dim xOutlookObj As Object
Dim xEmailObj As Object
Dim xUsedRng As Range
 
Set xSht = ActiveSheet
Set xFileDlg = Application.FileDialog(msoFileDialogFolderPicker)
With xFileDlg
.InitialFileName = Application.ActiveWorkbook.Path & "\"
End With

If xFileDlg.Show = True Then
   xFolder = xFileDlg.SelectedItems(1)
Else
   MsgBox "You must specify a folder to save the PDF into." & vbCrLf & vbCrLf & "Press OK to exit this macro.", vbCritical, "Must Specify Destination Folder"
   Exit Sub
End If
xFolder = xFolder + "\" + xSht.Name + ".pdf"
 
'Check if file already exist
If Len(Dir(xFolder)) > 0 Then
    xYesorNo = MsgBox(xFolder & " already exists." & vbCrLf & vbCrLf & "Do you want to overwrite it?", _
                      vbYesNo + vbQuestion, "File Exists")
    On Error Resume Next
    If xYesorNo = vbYes Then
        Kill xFolder
    Else
        MsgBox "if you don't overwrite the existing PDF, I can't continue." _
                    & vbCrLf & vbCrLf & "Press OK to exit this macro.", vbCritical, "Exiting Macro"
        Exit Sub
    End If
    If Err.Number <> 0 Then
        MsgBox "Unable to delete existing file.  Please make sure the file is not open or write protected." _
                    & vbCrLf & vbCrLf & "Press OK to exit this macro.", vbCritical, "Unable to Delete File"
        Exit Sub
    End If
End If
 
Set xUsedRng = xSht.UsedRange
If Application.WorksheetFunction.CountA(xUsedRng.Cells) <> 0 Then
    'Save as PDF file
    xSht.ExportAsFixedFormat Type:=xlTypePDF, Filename:=xFolder, Quality:=xlQualityStandard, OpenAfterPublish:=True
     
    'Create Outlook email
    Set xOutlookObj = CreateObject("Outlook.Application")
    Set xEmailObj = xOutlookObj.CreateItem(0)
    With xEmailObj
        .Display
        .To = Range("C17")
        .CC = ""
        .Subject = xSht.Name + ".pdf"
        .Attachments.Add xFolder
        If DisplayEmail = False Then
            '.Send
        End If
    End With
Else
  MsgBox "The active worksheet cannot be blank"
  Exit Sub
End If
End Sub
