[Parameter(Mandatory=$true,Position=0)]
[string]$Address1,
[Parameter(Mandatory=$true,Position=1)]
[string]$Address2,
[switch]$Recurse,
[switch]$Force
)
$ol = New-Object -comObject Outlook.Application
$mail = $ol.CreateItem(0)
$Mail.Recipients.Add($Address1)
$Mail.Recipients.Add($Address2)
$Mail.Subject = "DSC Deployment in Progress"
$Mail.Body = "There is a DSC install beginning. . ."
$Mail.Send()

You need to assign a value to the SendUsingAccount property. The account can be found in the (outlook).Session.Accounts collection.
$sendSmtpAddress = "some.name#somedomain.com"
$account = $ol.session.acounts | ? { $_.smtpAddress -eq $sendSmtpAddress }
then, assign to the SendUsingAccount property before sending
$mail.SendUsingAccount = $account
$mail.Send()
Full example
$sendSmtpAddress = "some.name#somedomain.com"
$ol = new-object -comobject "outlook.application"
$account = $ol.session.accounts | ? { $_.smtpAddress -eq $sendSmtpAddress }
$mail = $ol.CreateItem(0)
$mail.recipients.add("target.user#somedomain.com") | out-null
$mail.subject = "test email"
$mail.body = "test email"
$mail.SendUsingAccount = $account
$mail.Send()
For what it's worth, I gave up trying to send email via Outlook a long time ago, it's much easier to use plain SMTP. Depending on the security policy on your local SMTP server (Exchange?), you may be able to 'send as' any user on your local domain. Ask your IT people for the name/IP of an internal SMTP server that you can use to send email, and then it's as easy as:
send-mailmessage -smtpServer (servername or IP) -from sender.name#domain.com -to #(recipient1#domain.com, recipient2#domain.com) -subject "Email Subject" -body "Email Body"
If using send-mailmessage, it's possible to set a Display Name for the sender by using the form "Display Name <sender.name#domain.com>" e.g.
-from "Deployment Alerts <sender.name#domain.com>"
Recipients will see the Display Name in their email client, rather than the SMTP address.
A couple of points that I consider to be good practice:
Depending on the config of the SMTP server, there may be little, or no verification of the 'sender' address. It is worth using a genuine account that you have access to, so that you have sight of any bounce / non-delivery reports.
Consider including something in the mail body (perhaps a footer) that mentions where the alert came from and what process generated it. This can help your successor or colleague track down the script in the future.

Answer 2

The assignment like
$mail.SendUsingAccount = $account
worked for me since Windows Server 2000 till Windows Server 2008 and from Outlook 2007 till Outlook 2016. Since Windows Server 2016 I've got an exception (The server threw an exception. (Exception from HRESULT: 0x80010105 (RPC_E_SERVERFAULT))).
But there is an alternative way to assign this property.
[Void] $mail.GetType().InvokeMember("SendUsingAccount","SetProperty",$NULL,$mail,$account)
