The syntax doesn't change between the command line and a script file. What changes is how fast the commands are executed. If you're typing them in then there is plenty of delay between each command. But if they run from a script they get presented to Outlook much more quickly.

A simple way to fix this is add Sleep 1 (or similar) before the command that fails. Without seeing your error output I would guess that you want to sleep after CreateItem and maybe before Send. But if you look at the error messages closely you'll see they identify which line of the script failed. Put Sleep before the first line that failed. Retry the script. If a new line fails, then put a delay before it as well. If the first line still fails you can try Sleep 2. You can also make the Sleep shorter. For 1/2 second: Sleep -milliseconds 500.

IF adding Sleeps fixes the problems - in other words the problem is a synchronization issue, there may be something in the Outlook object model you could use that wouldn't be as hackish as using Sleeps.

I wasn't able to repro this on my Outlook 2010 installation. However I did look up an alternate method for sending email from PS (below). Maybe this method will work.

$i=$o.Session.folders.item(2).folders.item("Outbox").items.add(0)
$i.to="[email protected]"
$i.Subject="a wittle testy"
$i.Body="some body"
$i.send()
