The message QuickBooks is unable to send your email to Outlook denotes a problem with contact between QuickBooks and Outlook, which is frequently brought on by outdated software, faulty installations, or wrong settings. When trying to send emails straight from QuickBooks, such as reports or bills, users may run across this issue. Make sure Outlook is selected as the default email program, check QuickBooks email preferences, and make sure both apps are up to date in order to fix the issue. Software repair or reinstallation might also be helpful. Make an appointment with a professional QB by calling 1.855.856.0042.
