Hello there, kerryb1.
I reviewed our list of reported issues and found that it’s an outlook error. Our engineers are currently investigating and working on a permanent fix to this unusual behavior. I suggest reaching out to our Phone Support Team so we'll add your account to the notification list.
Here's how to contact us:
- Click Help and select QuickBooks Desktop Help.
- Enter in the box something like Unable to send invoices using Outlook.
- Click Continue.
- Select to either Chat, Call, or Get a callback.
We'll keep you updated via email. Let me know if you need anything else. Thanks!
