VBA 循環瀏覽電子郵件附件並根據給定條件保存

Question

這是對上一個問題的跟進（ VBA 從具有多個帳戶的電子郵件中保存附件（基於定義的標准） ）

場景：我有一個代碼，它遍歷某個 Outlook 帳戶中的所有電子郵件，並將附件保存到選定的文件夾中。 以前，我的問題是選擇從哪里提取附件的文件夾（和帳戶）（通過上一個問題的建議解決了這個問題）。

問題 1：代碼在該行顯示“類型不匹配”錯誤：

Set olMailItem = olFolder.Items(i)

問題 2：如問題標題所述，我的主要目標是遍歷所有附件並僅保存那些具有給定條件的附件（excel 文件，一個工作表名為“ASK”，一個名為“BID”）。 不僅僅是一個簡單的如果要考慮到這些標准，我必須將所有文件下載到“臨時文件夾”，進行選擇並將最終生成的文件放在輸出文件夾中，或者將所有文件下載到最終文件夾並刪除不符合標准。

問題：我似乎無法找到執行其中任何一個操作的方法。

問題：人們將如何做到這一點？ 這兩者中的哪一個更有效？

Dim olNameSpace As Object
Dim olMailItem As Outlook.MailItem

Dim sh As Worksheet
Dim LastRow As Integer

'delete content except from row 1
ThisWorkbook.Worksheets("FileNames").Rows(2 & ":" & ThisWorkbook.Worksheets("FileNames").Rows.count).Delete

'set foldername and subject
olFolderName = ThisWorkbook.Worksheets("Control").Range("D10")
'olSubject = ThisWorkbook.Worksheets("Control").Range("D16")

sPath = Application.FileDialog(msoFileDialogFolderPicker).Show
sPathstr = Application.FileDialog(msoFileDialogFolderPicker).SelectedItems(1)

Set olNameSpace = olApp.GetNamespace("MAPI")

'check if folder is subfolder or not and choose olFolder accordingly
'Set olFolder = olNameSpace.GetDefaultFolder(olFolderInbox).Folders(olFolderName)
Set olFolder = olNameSpace.Folders("email@email.com").Folders("Inbox")

If (olFolder = "") Then
    Set olFolder = olNameSpace.Folders("email@email.com").Folders("Inbox")
End If

'loop through mails
h = 2
For i = 1 To olFolder.Items.count
    Set olMailItem = olFolder.Items(i)

    'check if the search name is in the email subject
    'If (InStr(1, olMailItem.Subject, olSubject, vbTextCompare) <> 0) Then
    If (InStr(1, olMailItem.Sender, olSender, vbTextCompare) <> 0) Then

        With olMailItem

                strName = .Attachments.Item(j).DisplayName

                'check if file already exists
                If Not Dir(sPathstr & "\" & strName) = "" Then
                .Attachments(j).SaveAsFile sPathstr & "\" & "(1)" & strName
                ThisWorkbook.Worksheets("FileNames").Range("A" & h) = "(1)" & strName
                Else
                .Attachments(j).SaveAsFile sPathstr & "\" & strName
                ThisWorkbook.Worksheets("FileNames").Range("A" & h) = strName
                End If

                h = h + 1
            Next

        End With

    End If
Next 

Application.ScreenUpdating = True
MsgBox "Download complete!", vbInformation + vbOKOnly, "Done"

End Sub

Answer 1

問題 1：

您的文件夾中可能有這樣的會議邀請或除普通郵件之外的其他內容。
檢查Item的Class屬性，看是否是olMail

問題 2：

我將在這里進行錯誤處理：

1. 使用適當的名稱保存在臨時文件夾中
2. 打開文件
3. 嘗試到達床單
4. 如果有錯誤，只需關閉文件
5. 如果沒有錯誤，將文件保存在目標文件夾中
