Hi there, @lanceluttrell.

Thanks for joining this conversation. Allow me to chime in and help make sure your employees will receive emails from your QuickBooks Online (QBO).

If you already followed the steps shared by my colleague KlentB above and the issue persists, let's perform some troubleshooting steps to isolate this.

To start, have your employees use a private browser (incognito) and check their email from there. There are times that the browser is already full of frequently accessed page resources (cache and cookies), causing some unusual responses.

Here's how:

• Press Ctrl + Shift + N (Google Chrome).
• Ctrl + Shift + P (Firefox).
• Control + Option + P (Safari).

Once done, resend the email invitation. Refer to this article for further guidance: Add and manage users in QuickBooks Online.

If they receive the email, they can return to their default browser and perform a clear cache to refresh the system. However, if the issue persists, try using other supported browsers.

Let me know in the comment if you have further questions about this or anything else. I'm always here to help. Stay safe.
