Emailing documents from GP with Outlook 2010, Citrix XenApp

I have a customer accessing GP 2010 via the cloud (Citrix XenApp), using Accountable Forms Printer to generate and email sales invoices to customers. They want the invoices created by various GP users to be sent from a common email account, rather than the individual's personal Outlook account. Has anyone had any experience configuring such a scenario in the cloud?

Thanks in advance,
