从 VBA 搜索 Outlook 电子邮件

Question

给定的代码成功运行。它在 Outlook 已发送邮件文件夹中搜索电子邮件主题。搜索基于特定时间段内的特定日期进行。例如，下面的代码查找 2018 年 7 月 20 日上午 12:00 到晚上 11:59 之间发送的电子邮件标题“周五发送的测试电子邮件”。

除了我现有的搜索条件外，我如何过滤发送给特定用户的电子邮件。我想检查 [To] 字段。如果 [To] 有收件人 x@email.com、y@email.com 或 z@email.com，则不要返回搜索结果。如果 [To] 部分没有以下任一电子邮件，则搜索应返回“Yes. Email found”：x@email.com、y@email.com 或 z@email.com。

 Public Function is_email_sent()
    Dim olApp As Object
    Dim olNs As Object
    Dim olFldr As Object
    Dim olItms As Object
    Dim objItem As Object

    On Error Resume Next
    Set olApp = CreateObject("Outlook.Application")

    Set olNs = olApp.GetNamespace("MAPI")
    Set olFldr = olNs.Folders("myemail@example.com").Folders("Sent Items")

    Set olItms = olFldr.Items
    Set objItem = olItms.Restrict("[Subject] = ""Test Email Sent on Friday"" And [SentOn] >= ""7/20/2018 12:00 AM"" AND [SentOn] <= ""7/20/2018 11:59 PM""")
    If objItem.Count = 0 Then
        MsgBox "No. Email not found"
    Else
        MsgBox "Yes. Email found"
    End If

    Set olApp = Nothing
    Set olNs = Nothing
    Set olFldr = Nothing
    Set olItms = Nothing
    Set objItem = Nothing
End Function

这可能不是您所寻求的方法，但如果您将项目引用添加到 Outlook，您可以使用本机数据类型而不是将所有内容都视为对象，这样 Intellisense 就可以成为您最好的朋友。

优点是，您无需在Restrict 方法中猜测查询字符串是什么，而是可以简单地循环遍历所有邮件项目，然后使用本机属性来查找您要查找的邮件。这是您在上面确定的规格的示例。

 Public Function is_email_sent()
    Dim olApp As Outlook.Application
    Dim olNs As Outlook.Namespace
    Dim olFldr As Outlook.Folder
    Dim olItms As Outlook.Items
    Dim objItem As Outlook.MailItem
    Dim recipients() As String
    Dim found As Boolean

    found = False

    On Error Resume Next
    Set olApp = New Outlook.Application

    Set olNs = olApp.GetNamespace("MAPI")
    Set olFldr = olNs.Folders("myemail@example.com").Folders("Sent Items")

    For Each objItem In olFldr.Items
      If objItem.Subject = "Test Email Sent on Friday" And _
        objItem.SentOn >= DateSerial(2018, 7, 20) And _
        objItem.SentOn < DateSerial(2018, 7, 21) Then

          If InStr(objItem.To, "x@email.com") = 0 And _
            InStr(objItem.To, "y@email.com") = 0 And _
            InStr(objItem.To, "z@email.com") = 0 Then

              found = True
              Exit For

          End If

      End If
    Next objItem

当然，你可以去掉类引用，它仍然可以工作，但就像我说的，让 Intellisense 成为你的朋友。

有一些按顺序进行的微优化（即预先声明日期，而不是在每次循环迭代中运行 DateSerial），但这是为了证明我的观点的概念性想法。

您可以使用限制检查已找到的项目中的地址。

Public Function is_email_sent()

    Dim olApp As Object
    Dim olNs As Object

    Dim olFldr As Object
    Dim olFldrItms As Object    ' Outlook.Items

    Dim objResItems As Object   ' Outlook.Items
    Dim objResItem As Object

    'On Error Resume Next       ' Learn how to use this.

    Set olApp = CreateObject("Outlook.Application")

    Set olNs = olApp.GetNamespace("MAPI")
    Set olNs = GetNamespace("MAPI")

    Set olFldr = olNs.Folders("myemail@example.com").Folders("Sent Items")

    Set olFldrItms = olFldr.Items

    Set objResItems = olFldrItms.Restrict("[Subject] = ""Test Email Sent on Friday"" And [SentOn] >= ""7/20/2018 12:00 AM"" AND [SentOn] <= ""7/20/2018 11:59 PM""")

    If objResItems.count = 0 Then

        MsgBox "Email not found."

    Else

        For Each objResItem In objResItems

            Debug.Print objResItem.Subject
            Debug.Print objResItem.To

            If InStr(objResItem.To, "x@email.com") = 0 And _
              InStr(objResItem.To, "y@email.com") = 0 And _
              InStr(objResItem.To, "z@email.com") = 0 Then

                MsgBox "Email to " & objResItem.To & vbCr & vbCr & "No bad addresses."
                Exit For

            End If

            Debug.Print "At least one bad address in the mail."

        Next

    End If

    Set olApp = Nothing
    Set olNs = Nothing
    Set olFldr = Nothing

    Set olFldrItms = Nothing
    Set objResItems = Nothing

    Set objResItem = Nothing

End Function
