using powershell to send emails with different From addresses - powershell

Question

I use powershell to send emails from Outlook (complete automatic process). This work perfectly for the default mailbox. I have a lot of restrictions in the development network and can't use any software other than Outlook and powershell.
My question is: Is there a method to send email from a different account in outlook, using powershell
(in my Outlook I have three accounts A, B and C), even if i have one of the as predetermined.
The code that I use is this.
$o = New-Object -com Outlook.Application
$mail = $o.CreateItem(0)
$mail.importance = 2
$mail.subject = "SUBJECT"
$mail.body = "BODY"
$mail.To = "email001#xx.com;"
$mail.Send()
Is there a property I can set to make the email origin to be B or C, and not the predetermined A.

Answer 1

You need to set the SendUsingAccount property of the MailItem class which allows to set an Account object that represents the account under which the MailItem is to be sent. For example:
Sub SendUsingAccount()
Dim oAccount As Outlook.account
For Each oAccount In Application.Session.Accounts
If oAccount.AccountType = olPop3 Then
Dim oMail As Outlook.MailItem
Set oMail = Application.CreateItem(olMailItem)
oMail.Subject = "Sent using POP3 Account"
oMail.Recipients.Add ("someone#example.com")
oMail.Recipients.ResolveAll
oMail.SendUsingAccount = oAccount
oMail.Send
End If
Next
End Sub
Be aware, Microsoft does not currently recommend, and does not support, Automation of Microsoft Office applications from any unattended, non-interactive client application or component (including ASP, ASP.NET, DCOM, and NT Services), because Office may exhibit unstable behavior and/or deadlock when Office is run in this environment.
If you are building a solution that runs in a server-side context, you should try to use components that have been made safe for unattended execution. Or, you should try to find alternatives that allow at least part of the code to run client-side. If you use an Office application from a server-side solution, the application will lack many of the necessary capabilities to run successfully. Additionally, you will be taking risks with the stability of your overall solution. Read more about that in the Considerations for server-side Automation of Office article.
