Hello hammondelectric7,
Welcome to Community! QuickBooks Online makes it easy to email your forms to your customers. When the associated email addresses are not found, it can have a negative impact on your work. I would be glad to help!
I suggest accessing your QuickBooks Online account using a private browser. I also recommend clearing cache, to help improve system performance and web page loading times, or try another browser such as Firefox, Google Chrome, Edge, or Safari. In addition I recommend checking your customer list to ensure the email address is listed on their profile.
If you experience the same outcome, please contact us outside of Community. We would be happy to look into your situation in more depth, and escalate it for further investigation if necessary.
Feel free to reach out again, if you have any other questions. We would be happy to assist!
