When you open a Microsoft 365 file from Box on desktop, you may be prompted by a pop-up window to "Log in to grant access to Box."

After signing in once, you can collaborate in real time with your colleagues without needing to manually add Box as a Place. You can co-author Word, PowerPoint, and Excel files, and have all changes saved directly back to Box.
