👋 Hi @Laurene, welcome to the Box Community!
I’d be glad to assist with updating your domain and email address. For an in‑depth look at how to use this tool, please see our Domain Management, Verification, and Auto Enrollment article.
You may also want to check out this relevant topic in our community:
Once your new domain is claimed, you can proceed with updating the users’ email addresses. The Configuring and Editing Users guide provides the steps. Users’ authority levels, owned folders and files, and any shared links won’t be affected when their email address is changed.
If you’re having issues with the domain name or email change, please submit a ticket to our Product Support.
For purchasing new seats, see the Adding Seats To My Account guide. You may also email our Billing Team at billing@box.com if you need further assistance adding seats.
Looking forward to getting this sorted out!
