Outlook 中用于提取 Excel 附件的 VBA 代码

Question

我正在尝试将所有 xlsx 扩展文件从我收件箱中的未读电子邮件中下载到一个文件夹中，并将这些电子邮件标记为已读，并根据时间戳给出唯一的命名约定。

到目前为止，我所做的只是修改我在网上找到的代码

Sub GetAttachments()
' This Outlook macro checks a the Outlook Inbox for messages
' with attached files (of any type) and saves them to disk.
' NOTE: make sure the specified save folder exists before
' running the macro.
    On Error GoTo GetAttachments_err
' Declare variables
    Dim ns As NameSpace
    Dim Inbox As MAPIFolder
    Dim Item As Object
    Dim Atmt As Attachment
    Dim FileName As String
    Dim i As Integer
    Set ns = GetNamespace("MAPI")
    Set Inbox = ns.GetDefaultFolder(olFolderInbox)
    i = 0
' Check Inbox for messages and exit of none found
    If Inbox.Items.Count = 0 Then
        MsgBox "There are no messages in the Inbox.", vbInformation, _
               "Nothing Found"
        Exit Sub
    End If
' Check each message for attachments
    For Each Item In Inbox.Items
' Save any attachments found
        For Each Atmt In Item.Attachments

    If Right(Atmt.FileName, 4) = "xlsx" Then
            ' This path must exist! Change folder name as necessary.
                FileName = "C:\Users\vduraiswamy\Desktop\attachments\" & _
                    Format(Item.CreationTime, "yyyymmdd_hhnnss_") & Atmt.FileName
                Atmt.SaveAsFile FileName
                End If
                Next Atmt
    Next Item
' Check filename of each attachment and save if it has "xls" extension
            i = i + 1
' Show summary message
    If i > 0 Then
        MsgBox "I found " & i & " attached files." _
        & vbCrLf & "I have saved them into the C:\Users\vduraiswamy\Desktop\attachments." _
        & vbCrLf & vbCrLf & "Have a nice day.", vbInformation, "Finished!"
    Else
        MsgBox "I didn't find any attached files in your mail.", vbInformation, "Finished!"
    End If
' Clear memory
GetAttachments_exit:
    Set Atmt = Nothing
    Set Item = Nothing
    Set ns = Nothing
    Exit Sub
' Handle errors
GetAttachments_err:
    MsgBox "An unexpected error has occurred." _
        & vbCrLf & "Please note and report the following information." _
        & vbCrLf & "Macro Name: GetAttachments" _
        & vbCrLf & "Error Number: " & Err.Number _
        & vbCrLf & "Error Description: " & Err.Description _
        , vbCritical, "Error!"
    Resume GetAttachments_exit
End Sub

下载几个文件后，代码中途出现错误提示“无法对此类附件执行此操作”。

我还希望代码仅查看未读电子邮件。

尝试绕过不是文档的附件。

        End If
nonvalidAttachment:
    Next Atmt
Next Item

通常您会使用数字，但这里的数字不是恒定的，但描述是恒定的。

GetAttachments_err:

If Err.Description = "Outlook cannot perform this action on this type of attachment." Then
    Err.Clear
    Resume nonvalidAttachment
End if

MsgBox "An unexpected error has occurred." _
        & vbCrLf & "Please note and report the following information." _
        & vbCrLf & "Macro Name: GetAttachments" _
        & vbCrLf & "Error Number: " & Err.Number _
        & vbCrLf & "Error Description: " & Err.Description _
        , vbCritical, "Error!"
Resume GetAttachments_exit
