Dynamics 365 Layout is transitioning to Dynamics 365 Guides
Dynamics 365 Layout is no longer available to new customers. If you already have Layout, you’ll be able to use it until December 31, 2021, or the end of your subscription, whichever is earlier. A set of core Layout capabilities will be integrated into Dynamics 365 Guides in future release waves.
If you have questions, contact your account manager or visit the Guides forum.
