Hello kelsey5, 

I'm glad you've taken the time to reach out to us here in the Community. I'd be happy to help you get back on track.

When receiving an error message, it's important to complete some basic browser troubleshooting. These steps can often resolve the issue. I know how important it is for QuickBooks Online to be working as intended, so you can continue to focus on running your business.  

Give these steps a try: 

1. Clear your cache and cookies by using the following instructions: How do I clear my browser cache and temporary Internet files? Doing this will give your browser a clean slate and remove any bugs or stored Internet files that may be causing issues in QuickBooks Online.

2. Go Incognito. Incognito mode is a private browsing mode you can use with Google Chrome. Here's more information about what it is and how to use it: Browse in private.

3. Use a different browser all together. 

If you try all these steps and you're still seeing the error message regarding registering your email, please don't hesitate to reach back out to me in the comments below. We can work through this together to get this resolved for you. 

Have a great day!
