Saving an attachment from Outlook Mac2011 in OSX 10.6.8

I get the error

Microsoft Outlook got an error: item 1 of {attachment 1 of incoming message id 1579} doesn’t understand the save message.

[Sigh! worked ok in Entourage]

Does anyone know of a workaround or what I should be doing other than:

tell application “Microsoft Outlook”

...

set theseAttachments to (every attachment of thisInvoice)
repeat with thisAttachment in theseAttachments
	set AttachmentCheck to the name of thisAttachment
	if AttachmentCheck ends with ".pdf" then
		set myLocation to (myPath & AttachmentCheck) as text
		set mySavedPix to save thisAttachment in myLocation
	end if
end repeat

end tell

Try this. Works for me on Outlook 2011 in OSX 10.8.x

repeat with eachAttachment in eachMessage's attachments
						if name of eachAttachment contains ".xls" then
							set theAttachmentName to name of eachAttachment
							
							save eachAttachment in savePath
						end if
						
					end repeat
