Question

我有以下代码来计算Outlook中的电子邮件总数：

Sub Test()

    Dim objOutlook As Object, objnSpace As Object, objFolder As Object
    Dim EmailCount As Integer

    Set objOutlook = CreateObject("Outlook.Application")

    Set objnSpace = objOutlook.GetNamespace("MAPI")

    On Error Resume Next

    Set objFolder = objnSpace.Folders("MyFolder").Folders("Spam")

    If Err.Number <> 0 Then
        Err.Clear
        MsgBox "No such folder."
        Exit Sub
    End If

    EmailCount = objFolder.Items.Count
    Set objFolder = Nothing
    Set objnSpace = Nothing
    Set objOutlook = Nothing

    MsgBox "Number of emails in the folder: " & EmailCount, , "Number of spam messages "

End Sub

有人可以给我一些方法来计算一周中的某一天吗？

示例：

“星期一收到的信息数量= 476”
“星期日收到的讯息数量= 121”

甚至是特定日期

“2010年11月2日收到的电子邮件数量”

Answer 1

也许将参数（Optional dteDate As Date）添加到整个方法/函数中并在正文中包含以下代码

Select Case Weekday(dteDate)
  Case vbMonday  
    IsCorrectDay = True
  Case Else  
    IsCorrectDay = False
End Select

For Each MapiItem In MapiFolderInbox.Messages
  If MapiItem.TimeReceived = IsCorrectDay Then count = count + 1     
Next MapiItem

Answer 2

看起来你必须查看每条消息并使用TimeReceived属性。

For Each MapiItem In MapiFolderInbox.Messages
            If MapiItem.TimeReceived = dte Then count = count + 1
        Next MapiItem

或类似的东西。

这就是我所拥有的。似乎没有任何简单的属性或方法可以为您提供您想要的答案。我不知道是否有任何方法可以通过SQL查询引用邮件项目。如果有，这将是理想的方法。由于这似乎不可能，您只能选择迭代文件夹（或文件夹）中的所有项目，并为一周中的几天提供多个计数器变量。然后为每个项目增加适当的计数器。

主要问题是弄清楚如何引用适当的对象。

在MS Outlook 2003中测试过并且似乎正在运行。但是 - 我没有检查它是否正在计算收件箱的每个子文件夹中的每个项目，或者它是仅仅计算收件箱中的项目数，而不是收件箱的子文件夹中的任何项目。无论如何，她是：

 Set BUNCH_OF_Items = myInbox.Items
