Thank you for joining the conversation, WesterFence.

Upon checking our records, we haven't received any reported cases of a new outlook that is incompatible with QuickBooks Desktop (QBDT). If you see an error message "QuickBooks is unable to send your email to Outlook," this is usually just a settings issue.

We should modify your administrative privileges and verify that QuickBooks is not configured to run automatically with the administrator.

Here's how:

1. Close QuickBooks Desktop.
2. Open the Windows Start menu.
3. Type "QuickBooks" into the search. Then right-click the QuickBooks icon and select Open file location.
4. In the folder, right-click the QuickBooks.exe file and select Properties.
5. Click the Compatibility tab.
6. Select to uncheck the Run this program as Administrator option. If the option is grayed out, click Show Settings for All Users. This makes the option available.
7. Hit Apply and then OK.

Launch QuickBooks and proceed to send a test email or transaction. If you encounter any errors, proceed to Step 2 in this article: How to fix "Error: QuickBooks is unable to send your email to Outlook."

I also recommend referring to these articles to understand the optimal computer requirements for the best experience:

Please know that I'm always here if you have other questions about the new outlook. I wish you and your business continued success.
