I am trying to run this subroutine from an Excel Macro in a Scheduled job.

Private Sub SendMessage()
Dim OutApp As Object
Dim OutMail As Object
'ToStr, Subject and strBody are globals in the Excel VB Module.

Set OutApp = CreateObject("Outlook.Application")
Set OutMail = OutApp.CreateItem(0)
With OutMail
.To = ToStr
.CC = "xxx@yyy" 'Real address obscured here.
.BCC = ""
.Subject = Subject
.Body = strbody
.Send
End With
End Sub

It works perfectly when triggered by opening the spreadsheet which has an
auto run macro which invokes the code. Either manually from Excel or by
running the Command Line "C:\Program Files\Microsoft
Office\Office12\Excel.exe" /r "C:\Users\Alan\Documents\HSC\Fence Check\Fence
Check Auto Run.xlsm"

Normally the scheduled task that runs the same code (there is a bit more to
it) runs perfectly but when it hits the above it is failing and as a result
screwing up the scheduled job which then fails to complete and subsequently
will not run until after a reboot and re-registering the task.

Can anybody help or suggest a workaround. P.S. I always have Outlook Open on
my Desktop and I hate having to late bind the Objects in this code.

(Also posted in Outlook and Developer discussions but not got much response.)
