The Box for Slack integration enables you to share content from your Box repository in Slack. You get the ease of sharing and communication provided by the Slack platform, with the content management and security features of Box.
With the Box for Slack integration, you can adjust access with instant permissions to channel or chat participants. You are prompted to grant expanded permissions if not everyone in a Slack channel or group has permission in Box to view/access content you share in a Slack message.
Now it is also be possible to set the default way the Box for Slack app is adjusting those permissions. Inviting collaborators or creating a Shared Link happens automatically when channel members are unable to access a Box link you post, if you wish so. This means increased comfort of sharing Box content via Slack.
There is no needed admin level setup related to this enhancement.
