Mas Libman - Thank you for keeping this thread alive. One of my customers is having a problem. They are GCC (not High) and we are helping this test things in a small tenant where all users have G5 and EMS G5 licensed. UL Sensitivity Labels are available in S&C, and have been configured. They work correctly on Windows machines with the UL client loaded, but they do not work correctly on Mac machines. Below is are some (I hope) relevant bits of information that lead me to ask: Are UL labels supposed to be working in GCC? - The Unified Labeling activation (for label sync between classic and UL) is not present in the Azure portal. We've been told that the sync is not available for GCC, yet, but that UL sensitivity labels should work fine. - Every UL label that is not set for user permissions shows up in the Protection Templates in Azure (not in the labels, of course, as there is no sync running). I hope what I'm trying to say makes sense. For example, we have a head label called "Sensitive Information". A sub-label under that called "Sensitive Information - Company Users" that applies encryption allowing anyone in our company access to the file. We have another sub-label called "Sensitive Information - Custom" that lets the user choose the permissions when they apply the label. All of this is configured in UL. The "Sensitive Information - Company" label shows up as a Protection Template in Azure (the name shows up as a combination of the head label and the sub-label. "Sensitive Information - Sensitive Information - Company Users" in this example). The "Custom" label in UL does NOT show up in the Azure AIP Protection Template section. - There are no labels configured in Azure (there *were* labels, but we deleted them before configuring the UL labels) - In Mac Office apps, there is no Sensitivity button on display at all. We have even signed out of Office and signed back in (multiple Macs are experiencing this, all have Office 2019 pointed to the tenant). - In Mac Office apps, the "Protection" button will show what's contained in the Azure AIP Protection Template section (which lists the non-custom labels we defined in UL). We have a premier ticket open, but the going has been slow. I thought I would post here and just ask the general question around whether or not UL was supposed to be working in GCC. Thanks in advance.
