vba - 如何获取Outlook邮件的接收时间

Question

我需要从用户首选时间范围内收到的电子邮件中提取附件。

比如下午 2 点到 4 点之间收到的电子邮件的摘录。

请找到我已经完美提取文件的以下代码 - 但它确实适用于文件夹中的所有电子邮件。

请帮我解决一下。

Sub Unzip()

    Dim ns As NameSpace             'variables for the main functionality
    Dim Inbox As MAPIFolder
    Dim SubFolder As MAPIFolder
    Dim Atchmt As Attachment
    Dim FileName As Variant
    Dim msg As Outlook.MailItem


    Dim FSO As Object               'variables for unzipping
    Dim oApp As Object
    Dim FileNameFolder As Variant
    Dim Totalmsg As Object
    Dim oFrom
    Dim oEnd

    Set ns = GetNamespace("MAPI")
    Set Inbox = ns.GetDefaultFolder(olFolderInbox)
    Set SubFolder = Inbox.Folders("TEST")
    Set Totalmsg = msg.ReceivedTime
    oFrom = InputBox("Please give start time", ("Shadowserver report"))
    oEnd = InputBox("Please give End time", ("Shadowserver report"))

   If Totalmsg <= oFrom And Totalmsg >= oEnd Then
   For Each msg In SubFolder.Items
            For Each Atchmt In msg.Attachments
                    If (Right(Atchmt.FileName, 3) = "zip") Then
                    MsgBox "1"

                                    FileNameFolder = "C:\Users\xxxx\Documents\test\"
                                    FileName = FileNameFolder & Atchmt.FileName
                                    Atchmt.SaveAsFile FileName
                                    Set oApp = CreateObject("Shell.Application")
                                    oApp.NameSpace(FileNameFolder).CopyHere oApp.NameSpace(FileName).Items

                                    Kill (FileName)
                                    On Error Resume Next
                                    Set FSO = CreateObject("scripting.filesystemobject")
                                    FSO.deletefolder Environ("Temp") & "\Temporary Directory*", True
                    End If
             Next
    Next
End If
End Sub

进行了一些改进以提高性能和清晰度:

1. 测试消息循环内的接收时间
2. 将相关变量定义为日期(如 MsG.ReceivedTime)并改进了输入消息
3. 添加了Option Explicit以避免 future 编码中的错误(非常好的实践)
4. 使用 Environ$("USERPROFILE") 获取用户目录的路径
5. 在循环外重组变量和初始化
6. 添加了 LCase 以确保获取所有 zip(包括 .ZIP)

代码:
