Outlook.Application .send() does not send to specified recipients - outlook

Question

I'm attempting to write a simple powershell script that sends a meeting invite. It is creating the event on my calendar and it throws no errors, but it does not send the invite.
function CreateEvents($projectName, $recipient) {
$Outlook = New-Object -ComObject Outlook.Application
$NewEvent = $Outlook.CreateItem(1)
$NewEvent.meetingstatus.olMeeting
$NewEvent.Subject = "$($projectName) - Phase 1 planning"
$NewEvent.Body = "This could include anything like links or attachments."
$NewEvent.Location = 'Executive Conference Room'
$NewEvent.Start = [datetime]::Today.Adddays(1)
$NewEvent.Duration = 30
$NewEvent.Recipients("$($recipient)")
Write-Host "Sending to $($newEvent.Recipients)"
$NewEvent.send()
Write-Host $NewEvent.save()
}
Write-Host "Enter project name: " -NoNewline
[string]$projectName = Read-Host
Write-Host "Enter Receipient: " -NoNewline
[string]$recipient = Read-Host
CreateEvents $projectName $recipient
Full output
Enter project name:
asdf
Enter Receipient:
(redacted email)
Application : System.__ComObject
Class : 4
Session : System.__ComObject

What am I missing?
Update: Current code after adding attendee type and some try/catch blocks:
function CreateEvents($projectName, $recipient) {
$Outlook = New-Object -ComObject Outlook.Application
$NewEvent = $Outlook.CreateItem(1)
$NewEvent.meetingstatus.olMeeting
$NewEvent.Subject = "$($projectName) - Phase 1 planning"
$NewEvent.Body = "This could include anything like links or attachments."
$NewEvent.Location = 'Executive Conference Room'
$NewEvent.Start = [datetime]::Today.Adddays(1)
$NewEvent.Duration = 30
$RequiredAttendee = $NewEvent.Recipients.Add($recipient)
$RequiredAttendee.Type = 1
try {
$response = $NewEvent.save()
write-host "Saved"
} catch {
Write-Host "Save Error: $($response)"
}
try {
$response = $NewEvent.send()
write-host "Sent"
} catch {
Write-Host "Send Error: $($response)"
}
}
Write-Host "Enter project name: " -NoNewline
[string]$projectName = Read-Host
Write-Host "Enter Receipient: " -NoNewline
[string]$recipient = Read-Host
CreateEvents $projectName $recipient
Console:
Enter project name: asfd123
Enter Recipient: (redacted email)
Saved
Sent
No email is sent. The event shows up on my calendar and shows the target email in the attendees list, but it does not send anything. It is not in my sent items. It is not in my outbox. The recipient knows nothing about it.

In addition to setting up recipients of the meeting item you need to set up the Recipient.Type property of each recipient. The OlMeetingRecipientType enumeration lists all possible variants:
olOptional 2 Optional attendee
olOrganizer 0 Meeting organizer
olRequired 1 Required attendee
olResource 3 A resource such as a conference room
I am not familiar with PowerShell well enough, but the following VBA sample code shows the required sequence of property and method calls to send a meeting request:
Sub CreateAppt()
Dim myItem As Object
Dim myRequiredAttendee, myOptionalAttendee, myResourceAttendee As Outlook.Recipient
Set myItem = Application.CreateItem(olAppointmentItem)
myItem.MeetingStatus = olMeeting
myItem.Subject = "Strategy Meeting"
myItem.Location = "Conf Rm All Stars"
myItem.Start = #9/24/2009 1:30:00 PM#
myItem.Duration = 90
Set myRequiredAttendee = myItem.Recipients.Add("Eugene Astafiev")
myRequiredAttendee.Type = olRequired
Set myOptionalAttendee = myItem.Recipients.Add("User1")
myOptionalAttendee.Type = olOptional
Set myResourceAttendee = myItem.Recipients.Add("Room1")
myResourceAttendee.Type = olResource
myItem.Send
End Sub
