Hey there, ken6.
Thanks for taking the time to visit the Community today. I want to make sure you're able to get the new admin user added to your account.
Sometimes the invitation emails can get sorted to the spam folder. Please ask the new user to check their spam folder and make sure the invite isn't hiding out there.
If the email is not found in the spam folder, you may want to try resending the email. This article offers some pointers on what to do if the person you invited didn't receive their email: https://quickbooks.intuit.com/community/Account-management/Why-did-my-invited-users-not-receive-thei....
With this info you'll be able to get the new user added in no time. Keep up the great work and let me know if you have any other questions.
