Hello @CHRISD11,

Thank you for getting back and letting us know about the result. Allow me to step in and provide an update about the Outlook issue in QuickBooks Desktop.

The investigation about sending emails via Outlook is still ongoing, and our team has not declared a specific time frame for the complete fix. They're still working on it and conducting a further investigation because of the changes, but assured, we take cases like this with urgency and high regard.

I can see that my colleague's advice about running QuickBooks as Admin didn't work. When you run and email in QuickBooks, it also affects your Outlook program.

Aside from running our software as Admin, I suggest doing the same with your Outlook app. It helps ensure both the program have the same approval in terms the integration.

If you haven't contacted our QuickBooks Support Team, please do so they can add you to our list of affected users. This way, you can receive live email updates about this issue.

Our Customer Support Team for Pro, Premier, Plus is available from 6 AM - 6 PM PT (Monday - Friday). For Enterprise, any time, any day. See the steps to get a hold of a specialist:
