如何使用CDO使用VBA发送邮件//邮件服务器是具有代理的Exchange

问题描述

这是我在VBA上的实际代码...

This is my actual code on VBA...

Private Message As CDO.Message
Private Attachment, Expression, Matches, FilenameMatch, i

Sub enviar_mail()

    Set Message = New CDO.Message
    Message.Subject = "my subject here"
    Message.From = "[email protected]"
    Message.To = "[email protected]"
    Message.TextBody = "my text body here"

    Dim Configuration
    Set Configuration = CreateObject("CDO.Configuration")
    Configuration.Load -1 ' CDO Source Defaults
    Configuration.Fields.Item("http://schemas.microsoft.com/cdo/configuration/sendusing") = 2
    Configuration.Fields.Item("http://schemas.microsoft.com/cdo/configuration/smtpserver") = "my_mail_server" 'A
    'Configuration.Fields.Item("http://schemas.microsoft.com/cdo/configuration/smtpserverport") = 26
    Configuration.Fields.Item("http://schemas.microsoft.com/cdo/configuration/smtpauthenticate") = 1
    Configuration.Fields.Item("http://schemas.microsoft.com/cdo/configuration/sendusername") = "my_user"
    Configuration.Fields.Item("http://schemas.microsoft.com/cdo/configuration/sendpassword") = "my_pass"
    Configuration.Fields.Item("http://schemas.microsoft.com/cdo/configuration/smtpusessl") = True
    Configuration.Fields.Item("http://schemas.microsoft.com/cdo/configuration/urlproxyserver") = "my_url_proxy" 'B
    Configuration.Fields.Item("http://schemas.microsoft.com/cdo/configuration/urlproxyport") = "443" 'https
    Configuration.Fields.Item("http://schemas.microsoft.com/cdo/configuration/urlproxybypass") = "my_urlproxybypass" 'C

    Configuration.Fields.Update

    Set Message.Configuration = Configuration
    Message.Send
End Sub

当我运行子程序时，我收到以下消息:传输无法连接到服务器.

when I run the sub, i got this message: The transport failed to connect to the server.

这是我的代理配置

推荐答案

您尝试执行的操作不会成功，因为您正在查看MAPI/HTTP代理设置并尝试通过SMTP发送消息(这是两种不同的协议) .因此，您需要为Exchange服务器使用实际的SMTP设置(例如，它应该是端口25或客户端端口993)，或者如果您知道EWS终结点(例如Office365)，则可以考虑使用EWS

What your trying to do wont work because your looking at the MAPI/HTTP proxy setting and your trying to send the message via SMTP (these are two different protocols). So you need to use the actual SMTP setting for the Exchange server (eg it should be either port 25 or the client port 993) or you could look at using EWS instead if you know the EWS endpoint eg for Office365

Sub SendMessage(Subject As String, Recipient As String, Body As String, User As String, Password As String)
   Dim sReq As String
   Dim xmlMethod As String
   Dim XMLreq As New MSXML2.XMLHTTP60
   Dim EWSEndPoint As String
   EWSEndPoint = "https://outlook.office365.com/EWS/Exchange.asmx"
   sReq = "<?xml version=""1.0"" encoding=""UTF-8""?>" & vbCrLf
   sReq = sReq & "<soap:Envelope xmlns:soap=""http://schemas.xmlsoap.org/soap/envelope/"" xmlns:t=""http://schemas.microsoft.com/exchange/services/2006/types"">" & vbCrLf
   sReq = sReq & "<soap:Header>" & vbCrLf
   sReq = sReq & "<t:RequestServerVersion Version=""Exchange2010""/>" & vbCrLf
   sReq = sReq & "</soap:Header>" & vbCrLf
   sReq = sReq & "<soap:Body>" & vbCrLf
   sReq = sReq & "<CreateItem MessageDisposition=""SendAndSaveCopy"" xmlns=""http://schemas.microsoft.com/exchange/services/2006/messages"">" & vbCrLf
   sReq = sReq & "<SavedItemFolderId>" & vbCrLf
   sReq = sReq & "<t:DistinguishedFolderId Id=""sentitems"" />" & vbCrLf
   sReq = sReq & "</SavedItemFolderId>" & vbCrLf
   sReq = sReq & "<Items>" & vbCrLf
   sReq = sReq & "<t:Message>" & vbCrLf
   sReq = sReq & "<t:ItemClass>IPM.Note</t:ItemClass>" & vbCrLf
   sReq = sReq & "<t:Subject>" & Subject & "</t:Subject>" & vbCrLf
   sReq = sReq & "<t:Body BodyType=""Text"">" & Body & "</t:Body>" & vbCrLf
   sReq = sReq & "<t:ToRecipients>" & vbCrLf
   sReq = sReq & "  <t:Mailbox>" & vbCrLf
   sReq = sReq & "       <t:EmailAddress>" & Recipient & "</t:EmailAddress>" & vbCrLf
   sReq = sReq & "  </t:Mailbox>" & vbCrLf
   sReq = sReq & "</t:ToRecipients>" & vbCrLf
   sReq = sReq & "</t:Message>" & vbCrLf
   sReq = sReq & "</Items>" & vbCrLf
   sReq = sReq & "</CreateItem>" & vbCrLf
   sReq = sReq & "</soap:Body>" & vbCrLf
   sReq = sReq & "</soap:Envelope>" & vbCrLf
   xmlMethod = "POST"
   XMLreq.Open xmlMethod, EWSEndPoint, False, User, Password
   XMLreq.setRequestHeader "Content-Type", "text/xml; charset=""UTF-8"""
   XMLreq.setRequestHeader "Translate", "F"
   XMLreq.setRequestHeader "User-Agent", "Blah"
   XMLreq.send sReq
   If XMLreq.Status = 207 Then
   End If
End Sub
