I have a customer that has spent close to 6 hours on the phone with QuickBooks support dealing with an a failure in sending the accountants copy. This has worked previously and now it doesn't. The QuickBooks tech worked through the different problems that could cause this with no success. He/she finally changed a firewall rule and the copy was sent today it won't work. The rule is still set as it was. I have tried disabling the firewall to no avail. I verified that QuickBooks was able to access the internet. She is running QuickBooks Pro 14, Windows 7, and McAfee Security Center 13.6.1599. Any ideas will be appreciated.
