Question

Cannot invite user who belongs to a different enterprise

When provisioning users via Okta, we had one error for a specific user. That user was involved in Box testing for dev work, and that must’ve been in a different Enterprise.

An error occurred while assigning this app.

Automatic provisioning of user XXXX XXXX to app Box failed: Could not create new user. 409 - User with the specified login already exists

 

When manually trying to add the user, I see “Cannot invite user who belongs to a different enterprise” and cannot save.

 

How can we merge or close the duplicate user so that the user can be created in our Enterprise?

👋 Hi ​@Stellar-Billy, welcome to the Box Community!


When provisioning users via Okta or manually inviting them, encountering the 409 - error or the "Cannot invite user who belongs to a different enterprise" message indicates that the user's email address is already tied to an active Box account in another Box Enterprise.


If the user's account is locked inside another Enterprise (rather than a free/developer account), they must first contact the admin of that enterprise to have their account deleted or their email changed before you can invite them.


Alternatively, if the user wants to keep that Box account separate, they can log into that account and change its primary email address to a personal/private email (e.g., a Gmail address) that is not yet linked to any Box account.


Once their corporate email address is freed up, Okta provisioning and manual invitations in your Enterprise will succeed immediately.
