Sales Order Entry allows the user to choose File, Send and a popup box will allow you to send the quote or order acknowledgement to the ordering contact, ship to contact, bill to contact and/or to the sales rep. You can fax it to some and email it to others. That's a typical example of the power of the Mail module.
The most common way to implement this functionality is via a Carillon supplied Windows server-side process that interfaces to Microsoft Outlook and Microsoft Exchange on the server.
For emails, the forms/documents are sent as Adobe Acrobat (PDF) attachments.
