When you share a snapshot of a tile from the Power BI mobile app for Windows 10, your recipients see the snapshot of the tile exactly as it was when you sent the mail. They can't open the dashboard. You can send snapshots of tiles to anyone — not just colleagues in the same email domain.

Tap a tile to open it in focus mode.
Tap the share icon in the bar at the top of the tile.
Share the tile from any sharing app you have on your Windows 10 device.
