Hi there, @shay13.

Let me share with you the possible reason why you're getting this error message and provide you an immediate solution to this.

As mentioned above, you may run into this issue if your registry key is corrupted. This error may occur when you send an email from a third-party app using Microsoft Outlook. 

Also, QuickBooks updates are intended to improve the program's functionality and resolve various issues. Thus, this makes sure that the product is always compatible with the applications that it's integrated. Having said, we can assure you that this concern isn't related to any product updates. 

To resolve this concern, make sure to set Outlook as the default mail client. You can also run a repair tool on Microsoft Office or uninstall and reinstall it to clean its registry and preferences.

Before taking these actions, I highly suggest contacting a Microsoft IT Expert so they can provide you the proper steps. This way, we can avoid damaging your computer's operating system.
