Simplify custom objects for messages

[AdhocAdam]

With each new message class introduced, a doubling of efforts is created with constant re-use of the same PSCustomObjects created (e.g. $email and $calAppt).

It would make more sense to throw these into a PowerShell class to increase code re-use and would introduce the need to raise the minimum PowerShell version of this script/runbook to v5.

Instead of a Class, this could also be improved with a function still resulting in fewer lines of PowerShell. The following is a proposed idea.

function New-SMEXCOMessage ($ExchangeMessage)
{
    $smexcoMessage = New-Object System.Object 
    $smexcoMessage | Add-Member -type NoteProperty -name From -value $ExchangeMessage.From.Address
    $smexcoMessage | Add-Member -type NoteProperty -name To -value $ExchangeMessage.ToRecipients
    $smexcoMessage | Add-Member -type NoteProperty -name CC -value $ExchangeMessage.CcRecipients
    $smexcoMessage | Add-Member -type NoteProperty -name Subject -value $ExchangeMessage.Subject
    $smexcoMessage | Add-Member -type NoteProperty -name Attachments -value $ExchangeMessage.Attachments
    $smexcoMessage | Add-Member -type NoteProperty -name Body -value $ExchangeMessage.Body.Text
    $smexcoMessage | Add-Member -type NoteProperty -name DateTimeSent -Value $ExchangeMessage.DateTimeSent
    $smexcoMessage | Add-Member -type NoteProperty -name DateTimeReceived -Value $ExchangeMessage.DateTimeReceived
    $smexcoMessage | Add-Member -type NoteProperty -name ID -Value $ExchangeMessage.ID
    $smexcoMessage | Add-Member -type NoteProperty -name ConversationID -Value $ExchangeMessage.ConversationID
    $smexcoMessage | Add-Member -type NoteProperty -name ConversationTopic -Value $ExchangeMessage.ConversationTopic
    $smexcoMessage | Add-Member -type NoteProperty -name ItemClass -Value $ExchangeMessage.ItemClass

    #if these properties exist, it's an Appointment
    if ($ExchangeMessage.Start) {$smexcoMessage | Add-Member -type NoteProperty -name StartTime -Value $ExchangeMessage.Start}
    if ($ExchangeMessage.End) {$smexcoMessage | Add-Member -type NoteProperty -name EndTime -Value $ExchangeMessage.End}

    return $smexcoMessage
}
