If you have over 25 CRM users with professional CALs and have been using a CRM 2013 online free development environment, you may have noticed that the navigation bar has become a sickly vomity orange colour in the past few weeks. Now you can distinguish between your production CRM online instance and your non-production instance by the colour of the navbar. In case this confused you and you thought you had entered a parallel universe, they have also helpfully added the word ‘Sandbox’ in the middle of the navbar which gets bigger if you click it. This is undoubtedly useful and will hopefully prevent you from messing up some live data by accident. More details on Sandbox environments can be found on Mike Carters CRM Online product team blog.
However, what if you are using CRM 2013 on-premise and want to highlight to a user that they are working on a different environment. Well, it looks like this Sandbox code has also made it into CRM 2013 Rollup 2, so it can be enabled somewhat, though not in a supported way.
