  • I cannot set a custom subdomain – this needs to be enabled ASAP as it drives the SSO setup

Hi ​@Swarm Aero 👋 Welcome to the Box Community!

 

Custom subdomains are not available for any trial accounts. I see that someone from your organization has already reached out to our Billing Team to convert the trial account to live. Please keep an eye out for their response so they can continue assisting you.


To help verify and expedite the process, we recommend replying to the ticket using your admin’s email address to authorize the request.


Additionally, if you need further assistance setting up your custom subdomain after the conversion, feel free to submit a ticket to our Product Support team. For more information about custom subdomains, please visit: Enterprise Settings: Custom Setup Tab.

 

Thanks, and have a great day! 😊

The subdomain option documented here[1] is not available in my business plus account. I need to add that to enable SSO. Please advise.

👋 Hi ​@bboptex, welcome to the Box Community! I’ve moved your post to this relevant thread.

 

Custom subdomains are not available for any trial accounts which is also stated on that support article. Custom subdomain will be available once your account goes live.


If you need further assistance setting up your custom subdomain after the trial has ended, feel free to submit a ticket to our Product Support.

 

Thank you!
