Creating a MS Outlook 2010 mail message from Powerbuilder only works when Outlook is closed

Hi
I am using Powerbuilder 11.5 and have updated the code to handle MS Outlook 2010.

The code used to work fine with earlier versions of Outlook and allowed the user to send emails from Powerbuilder with either Outlook running or not running, but does not work now since the Outlook version change when Outlook is running.  The code works fine when Outlook is not running.

updated version not working when Outlook open
HKEY_LOCAL_MACHINE\Software\Microsoft\Office\14.0\Outlook\InstallRoot

previous working version of Outlook
HKEY_LOCAL_MACHINE\Software\Microsoft\Office\10.0\Outlook\InstallRoot


The code is as follows;

//Declaration
OLEObject myoleobject, db, doc, rt_item, loo_ol_msg_cast

myoleobject = CREATE OLEObject
//  loop for two minutes, or until notes is started successfully
t_StartTime=Now() //wait 2 min for Notes to load ...
Do
	Yield()	//yeld control occasionally
	SetPointer(hourglass!)
	iResult = myoleobject.ConnectToNewObject("outlook.application")	
	If iResult = 0 Then Exit	//OK, Outlook is active
	Yield()
Loop Until SecondsAfter(t_Starttime, now()) > 120	//try again in #sec

if iResult <> 0 then
	f_user_error("Could not open Microsoft Outlook")
	return FALSE
end if

loo_ol_msg_cast = myoleobject.CreateItem(0)

Select allOpen in new window

The code fails on the above line (CreateItem) when MSOutlook is running
This works fine when MSOutlook is closed - the mail is generated and sent

I cannot find what is needed to allow a new mail to be generated when MS Outlook is open - I would be really grateful for any assistance - thanks Wingmanshaks
