With this new Box for Microsoft Teams enhancement, users can drag and drop their files from their desktop to the Teams chat or channel post window for seamless upload and sharing of their content into Box. All files are automatically saved to Box in the folder associated to that chat or channel.
Please note, drag and drop to Box is only available in chats and public channels (Private and shared channels with drag and drop is targeted for later this year).
To enable drag and drop, admins need to run this Powershell script. Once enablement is complete, whenever a user drags and drops a file in a chat or public channel, it will be uploaded to Box.
