Welcome to the Community, GPharris.
Currently, only one email address can be linked with each Intuit account user profile. There's another option where you can create users without using email addresses. This may come in handy for what you're trying to accomplish.
Here's how to create a user with no email attached to their profile:
- In your top menu bar, go to Company, then Users.
- Click Set Up Users and Roles.
- Enter the admin password and hit OK.
- Access your User List tab, then press New.
- Enter a user name and an optional password.
- In the Available Roles section, specify this user's roles.
- Select Add, then OK.
I've also included a detailed resource about creating and managing users which may come in handy moving forward: Create/manage users & roles
I'll be here to help if there's any additional questions. Have an awesome Wednesday!
