Dynamics 365 for Outlook vs Editable grids

Hi,

I'm trying to use editable grids in Dynamics 365 (8.2) on-premise inside Dynamics 365 for outlook. If I'm online, the grid is rendered only after page refresh. In offline mode it's not rendered at all. I don't see any restrictions for them in Dynamics 365 for Outlook at any Microsoft site. Anyone experienced this?
