According to this URL, "Built-in labels require a subscription edition of Office apps. If you have standalone editions of Office, sometimes called "Office Perpetual", we recommend you upgrade to Microsoft 365 Apps for Enterprise to benefit from the latest labeling capabilities." https://docs.microsoft.com/en-us/microsoft-365/compliance/sensitivity-labels-aip?view=o365-worldwide...
Now, I just spoke to a MS Sales rep online who told me that even though we have the E5 license, we will also need to purchase the 'Microsoft 365 Apps for Enterprise' in order to use the AIP built-in labels.
Surely that is not the case? Could someone please clarify this?
