Hello, @EBMECH12.

I understand the importance of being able to send invoices seamlessly. As I've checked from our records and found a new investigation about this error when emailing forms and transactions from QuickBooks Desktop. Our engineers are now all hands on deck working together to fix the problem as quickly as possible.

If you haven't been added to the list of affected uses in this investigation (INV-45586), I encourage reaching out to our Support Team. Once added, you'll automatically receive an email notification with the latest updates. To contact support, check out this link: Contact the QuickBooks Desktop Customer Support Team.

Post again if you have any other questions. I'm a post away to help. Have a good day!
