VBScript abort when outlook is closed.

Question

Hello, I am using the folowing vbscript to send email. It works fine only when the outlook is open in the machine, the operation is aborted when the outlook is closed. Any suggestion on it? I thought the script should start outlook by itself
if the is not running. Thanks for your help! 
Set MyApp = CreateObject("Outlook.Application")
Set MyItem = MyApp.CreateItem(0)
With MyItem
.To = "[email protected]"
.Subject = "Subject"
.ReadReceiptRequested = False
.HTMLBody = "MessageLine 2"
End With
MyItem.Send

if you have a valid SMTP server you could use the following 
Dim mailer : Set mailer = CreateObject("CDO.Message")
mailer.Configuration.Fields.Item ("http://schemas.microsoft.com/cdo/configuration/sendusing") = 2
mailer.Configuration.Fields.Item ("http://schemas.microsoft.com/cdo/configuration/smtpserver") = "smtpserver.domain.com" 
mailer.Configuration.Fields.Item ("http://schemas.microsoft.com/cdo/configuration/smtpserverport") = 25
mailer.Configuration.Fields.Item ("http://schemas.microsoft.com/cdo/configuration/sendemailaddress") = "[email protected]"
mailer.Configuration.Fields.Update
mailer.From = "[email protected]"
mailer.To = "[email protected]"
mailer.Subject = " subject"
mailer.Textbody = "contenttext"
mailer.AddAttachment "C:\temp\attachment.txt"
mailer.Send
