Hi ​@Jon, 

Welcome to Box Community! We’ll go ahead and verify if the user can be added to your Enterprise. 

In order to do so, I’ll go ahead and create a new case and someone from Box Product Support team will reach out to you through email. Please keep an eye out and we will be in touch. 

Thanks for taking the time, and stay well! 

I am trying to add a new user and am unable with the message "User belongs to another enterprise". The user is not sure what that other enterprise would be. He had created using his office email for development purpose. However, i would like to provide him the enterprise license. Looks like there is a conflict here because i am using the same office email of my colleague. Please help.

Hi ​@uthayanan, 

Welcome to Box Community, and we’d love to resolve adding new user error. 

The “User belongs to another enterprise” error when adding users typically occurs because the user you are trying to add already has a Box account associated with a different enterprise. 

Please note you cannot invite a user with Business-level account. The end user must contact his/her primary admin. 

To have a closer look, we suggest on contacting our Box Product Support team and submit a new case through this support link. 

Thanks for posting, and we hope get this sorted very soon!
