Have just installed new Win 7 WS (64bit) replacing XP WS.
Had been able to e-mail invoice prior to new install.
Using Outlook 2007, Order Entry Version 8.1D.
On the XP WS, when an invoice was sent by e-mail, Outlook would open and the PDF generated by OE was sent as an attachment.
On the Win 7 WS, Outlook does does not open, however the e-mail is sent but without the attachment.
If you then go to the sent folder in outlook, the e-mail is there with the attachment.
So the customer is not receiving the attachment.
We are using the MAPI method to send.
