We’re excited about new CRM Online functionality that you’ll soon see. Recently, you may have noticed changes to the navigation bar at the top of one or more of your Dynamics CRM Online instances. For both free and paid test instances, you’ll now see an orange navigation bar with a SANDBOX watermark. Production instances will continue to display the blue bar you’ve come to expect.
The product team has written a robust blog post that covers what this change means to you and how this relates to some new capabilities we’ll be releasing in the near future.
