Hi ​@dunncreek, welcome to the Box Community!

If you’re looking to convert a co-worker (i.e., an unmanaged user) to a managed user on your enterprise account, please refer to the following guide: Converting Unmanaged Users to Managed Users.

Note:​​​​​

• When you convert an unmanaged user to a managed user, they receive a notification about joining your organization 14 days before the conversion. If the user does not want to join your organization, they can change the primary email address for that account to a private one. If they do not perform any action, their account is automatically converted.
   
• Alternatively, if the unmanaged users that you want to convert to managed users have active email inboxes associated with their Box accounts, you can expedite their migration by sending them invitations to join your enterprise. This method provides immediate access to Box.

If you encounter any errors during the process, kindly share the exact message with us so we can take a closer look.

Looking forward to helping you get this sorted out!
