如何使用 RDCOMClient 从辅助帐户发送 Outlook 电子邮件 - 翻译现有的 VBA 代码？

Question

我正在尝试使用 从辅助电子邮件地址发送电子邮件RDCOMClient。我听取了如何使用 R RDCOMClient 检索 Outlook 收件箱电子邮件？并尝试用 VBA 编写并翻译，但无法获得正确的命令。

注意：我无法使用，SentOnBehalfOfName因为我没有必要的权限。

以下 VBA 和 Python 代码均成功从辅助收件箱发送电子邮件。

编程语言

Sub SendUsingAccount()

 Dim oAccount As Outlook.Account
 Dim oMail As Outlook.MailItem
 Set oAccount = Application.Session.Accounts.Item(2) 'Index of Mailbox
 Set oMail = Application.CreateItem(olMailItem)
 oMail.Subject = "Sent using MAPI Account"
 oMail.Recipients.Add "email@email.com"
 oMail.Recipients.ResolveAll
 oMail.SendUsingAccount = oAccount
 oMail.Send
End Sub

Python

import win32com.client
o = win32com.client.Dispatch("Outlook.Application")
oacctouse = None
for oacc in o.Session.Accounts:
  if oacc.SmtpAddress == "myemail@email.com":
    oacctouse = oacc
    break

#print oacc   
#dir(oacc)
#oacc.CLSID
#oacc.GetAddressEntryFromID
Msg = o.CreateItem(0)
if oacctouse:
   Msg._oleobj_.Invoke(*(64209, 0, 8, 0, oacctouse))  # Msg.SendUsingAccount = oacctouse
Msg.To="email@email.com"    
Msg.HTMLBody = "test env instance #"
Msg.Send()

右

除了猜测我能想到的所有组合之外，我在 R 中尝试过的[["SMTP"]]事情$SmtpAddress：

OutApp <- COMCreate("Outlook.Application")
outMail <- OutApp$CreateItem(0)
#1 :No Error, but email sends from primary inbox
oa<-OutApp[["Session"]][["Accounts"]]
second_inbox<-oa$Item(2) 
outMail[["SendUsingAccount"]]=second_inbox
#2: Runs, but sends from primary inbox
outMail[["SendUsingAccount"]]="myemail@email.com"
#From what I read emails need to be accessed with a number,not the name
#3 Runs, but sends from primary inbox (the Python index changes every run)
outMail[["SendUsingAccount"]]="oacc_id_from_Python"

#Rest of reproducible code
outMail[["To"]] = "email@email.com"
outMail[["subject"]] = "Alt Acc"
outMail[["body"]] = "test"
outMail$Send()

# Send the message from an alternate account
Email[["sentonbehalfofname"]] = "alternate-sender@test.com"

这家伙成功了。:)
