Who granted access

Hi Lisa, 

Welcome to the Box Community!

Box Admins may run a User Activity Report to determine who granted access to a folder owned by any of their managed users.

To run this report, go to Admin Console> Reports > User Activity > leave the Users or Groups field blank > then input the Start Date and End date of the period you need to investigate  > and then under Action Types choose the following parameters:

• Action type: Collaboration - choose "Accepted invite", "Invited collaborator"

Click "Run" and wait for the report to export, once available filter the report using the folder name and that's it!

Let us know if there is anything else we may assists you with and we will help you!

Best,
