After about a month of work I have gotten AIP running for a test group of users. I made a teaching sheet beforehand on how to use the labeling system a long time ago, but noticed that the label toolbar is now missing. When I made the sheet I was running Office 365 ProPlus with MAYBE AIP UL client, I don't remember. Now we are running Office 365 Business with the AIP UL client and the toolbar is missing. I also noticed the the button in the ribbon was changed from "Protect" to "Sensitivity".
I checked my settings in Azure policies and the bar is set to enabled. Is the business edition not able to receive the AIP tool bar or is the UL client only using UL policies that don't include the toolbar option in them?
