So this whole time I was told the issue was known and being worked on and in fact it is not?

All those faxes you list were previously gone through and confirmed.  Uninstalled both QuickBooks and Office, reinstalled.  Gone through the repairs.  Spent several hours with QB support confirming all the settings.  Spoke with both QB support and Microsoft supports and was assured QB was aware and working on the issue.  I use this feature almost daily to send out invoices and keep track of what's been sent and when.  The feature crashed Outlook almost every 3 email being set out.  How do we get QB to look at this issue and start to find a repair?
