Hello @Zilbruin, welcome to the Box Community!
Our Billing Support team can definitely review your eligibility to reactivate your Box account. To help resolve your concern, please open a support case with our Billing Team or email them at billing@box.com using the email associated with the affected account for verification.
Currently, only business-level Box accounts have the ability to reactivate online. Apologies for any limitations. For more information and to learn about the criteria for online reactivation, please see 'Reactivating Your Box Account.'
Looking forward to resolving this for you.
Kindly let us know if you have any other questions. 
I would like to continue using the account that is associated with this email address.
I accidentally deleted the account, but when I try to restore it, I get the following message and cannot recover it:
> An error occurred while processing your request.
> The account associated with this email address cannot be reactivated online.
> Please contact the Billing Support team (+1 650 329 1210 or [billing@box.com](mailto:billing@box.com)).
Could you please let me know what I should do in order to restore my account?
Dear @tk-kw, welcome to the Box Community! I’ve moved your post to this related topic.
Currently, only business-level Box accounts have the ability to reactivate online. To assist you with manual reactivation, kindly email our Billing Team at billing@box.com. For verification purposes, please ensure that you contact us using the email address associated with the affected account.
Additionally, I’d like to address the concern you raised in your related support ticket regarding reactivation and email changes. While I understand there are some challenges with claiming the domain, this information would be helpful for future reference if you decide to update the email address on another account.
For the existing personal account currently associated with the email you wish to use, make sure it’s active. Add a new email from your account settings then set it as primary. Remove the original email so it can be released from the personal account.
You can refer to our guide on Login and Email Addresses.
For the target account, Add a Managed Domain first as part of our Box Zero Trust Enhancement. Once the domain is claimed, you may proceed with updating the email address.
Thank you, and wishing you a wonderful day!
