I recently switched from Qutlook to Windows Live Mail. I use QuickBooks Pro 2012 and have Windows 7 for an operating system. My problem is that Live Mail does not create a "sent mail" folder for the documents I e-mail from QuickBooks. I have contacted QuickBooks tech support and they said to contact Microsoft to find out if Live Mail supports 3rd party software. I cannot seem to find a phone number to ask Microsoft the question and the one person I did reach for chat help said he could not answer the question and directed me here. Does anyone know if Live Mail supports 3rd party software?
