Hi, my invoices are not sending. I get the error message, “Invoice failed to deliver” I have tried sending to numerous email addresses that I know work.

It's my priority to help you send your invoices from QuickBooks Online (QBO), @euan-emfs-tech. Let me give updates about this error Invoice failed to deliver.

I know it wasn't ideal to get unexpected results while working on your transactions. I want you to know that this has been a priority of our engineering team, and they're currently working on a resolution as quickly as possible. While the investigation is still in progress, I recommend sending your invoices manually outside of QuickBooks.

Here's how:

1. Open your transaction, then click on Print or Preview.
2. Tap on Download, then save the file.
3. Attach the file to your email, then send it to your customer.

We'll share updates on our progress. You may also visit this link to see the status of the error: https://status.quickbooks.intuit.com/.

Please extend your patience about this matter, and I hope to get everything up and running soon. If you have other questions, please let me know by leaving a comment below. I'm more than happy to help you again. Keep safe!
