Microsoft Retires AIP Add-On for Office

Microsoft has announced the retirement of the unified labeling client on April 11, 2024. The client, also known as the AIP add-on for Office, went into maintenance mode on January 1, 2022, so it’s unsurprising that this development should happen. Users get better functionality by using the built-in information protection features in the subscription versions of Office, so there’s no real need to keep the unified labeling client around – apart from migrating users, that is.
