The benefits of deploying built-in labeling within Microsoft 365 apps

Published May 11 2021 11:02 AM 9,286 Views

During 2016, Microsoft introduced a new product that allowed organizations to implement a sensitivity label taxonomy and empower information workers to leverage these and apply them to documents or emails as part of daily work. This product is known as “Azure Information Protection (AIP)” and uses a client application for the Windows platform which deployed an add-in within Office apps including introducing a new “Sensitivity” button that can be used by information workers to flag documents and emails according to their sensitivity.

Since then, Microsoft’s information protection platform has evolved, implemented across all common platforms (MacOS, iOS, Android, Web) and the Azure Information Protection Client with rich capabilities across Microsoft 365 and is now under the wide umbrella of Microsoft Information Protection offering.

The main change as part of the transition to Microsoft Information Protection is that sensitivity labels are available across all common platforms and do not require an add-in or additional implementation, they are just part of the service offering. If you are using Microsoft 365 apps for Enterprise (formerly known as Office 365 Professional Plus) and you deployed sensitivity labels within your organization, no additional deployment stage is required. The same “Sensitivity” button is now exposed within the application ribbon. This integration is applicable consistently to all supported platforms. Moving forward, this integrated capability is to be known as “Built-in sensitivity labeling.”

Benefits to moving from client-based labeling to built-in labeling.

Using built-in labeling is seamless and does not require any management overhead in addition to cloud-based policy configuration. As part of your existing Microsoft 365 apps deployment, the bits are already available for every information worker without the need for installing additional components. The important aspects to consider are:

  1. No need to test, deploy and update another application or add-in within your endpoints. You leverage the deployment stage as part of ongoing or existing Microsoft 365 app project.
  2. Microsoft 365 apps will work with improved performance since no add-in needs to be loaded and all labeling functionality runs inside the application itself.
  3. Updates are being pushed as part of Microsoft 365 apps releases.
  4. Seamless experience across all Microsoft 365 platforms.

This is in line with other initiatives at Microsoft to provide built-in functionality that reduces or eliminates the need to deploy and maintain add-ins and plugins for other security and compliance-related functionality, which can potentially reduce an IT department’s challenges while providing a better user experience with more performance and stability to end users across workloads.

So, what is the Azure Information Protection Client, and should I continue to use it (or consider deploying it)?

Azure Information Protection Client (or Unified Labeling Client) is an application package for the Windows platform that include 4 components:

  1. Azure Information Protection add-in for Microsoft 365 apps
  2. Classify and protect (Ability to apply and consume labels outside Microsoft 365 apps) via a File Explorer extension
  3. Azure Information Protection viewer (to consume Non-Microsoft protected documents)
  4. Azure Information Protection PowerShell cmdlets to apply and consume labels.

Using built-in labeling replaces the first item in the list which is the Azure Information Protection add-in. Other components (described in number two, three, and four) can still be deployed without any dependency on the add-in portion of Azure Information Protection.

If you are using the Azure Information Protection add-in today and wish to use built-in sensitivity labeling instead to gain the benefits described above, then you can disable the add-in, uninstall the complete client, or control the behavior with a group policy. You have the choice to select the best approach which fits your business use cases and needs.

If you are NOT using the Azure Information Protection add-in today and looking to implement sensitivity labels across your organization, we recommend starting directly with built-in sensitivity labeling and deploy Azure Information Protection Client components (items described in number two, three, and four) if desired, but without enabling the AIP plugin for Office apps.

Where is built-in labeling available today?

Built-in labeling is already available and in use as part of your deployment of sensitivity labels in MacOS, iOS, Android, and web apps. If you deployed your sensitivity labels policies then these are already enabled and deployed (Web apps integration need to be enabled separately as documented). The main requirement here is to ensure that you are using the right Microsoft 365 apps for Windows that support this capability.

Built-in labeling in Microsoft 365 apps for Windows is available in all updated releases with versions newer than 1910+. (How to check your version of Microsoft 365 apps). If you are using an up to date version, no matter if you use Current Channel or Semi-Annual Channel, the capability is there and operational.

We do recommend ensuring your organization Microsoft 365 apps update channel is set to Current Channel or Monthly-Enterprise channel. These channels get the latest and greatest features in a shorter time frame. If your organization is using the Semi-Annual channel, then updates are deferred for a later period. Read more about Microsoft 365 Apps update channels here.


Deployment method

Once you have ensured you are using a version of Microsoft 365 apps that is released after 1910 in your organization, all you need to do is to implement your labeling taxonomy in the Microsoft 365 Compliance portal and publish your labels. You can use the official documentation to understand more on the backend configurations that need to....

If you do want to use Azure Information Protection client capabilities side by side with built-in labeling (referring to PowerShell module, Classify & Protect app and, AIP Viewer), you can download and deploy the Azure Information Protection unified labeling client (available to be downloaded from this link). Then configure a Group Policy to ensure that built-in labeling will always override and disable the Azure Information Protection add-in component. Read more about how to configure the group policy here. With this deployment approach you can enjoy both from the benefits of using built-in labeling and additional components.


Feature parity

Azure Information Protection Client and built-in labeling for Microsoft 365 apps do not have feature parity today. As we move forward, built-in labeling will add more capabilities which are currently available in the Azure Information Protection client. It is important to understand that the key features available, which include:

Feature marked as :star: are exclusive to built-in labeling with Microsoft 365 apps.

In addition, see complete roadmap and timelines for additional features within built-in labeling for Microsoft 365 apps here.

Additional considerations

In perpetual versions of Microsoft 365 apps (Office 2013, 2016, 2019) built-in labeling is not included, so if you are using one of these versions you will need to use the Azure Information Protection client and add-in for Office instead.

Do note that using built-in labeling does require sensitivity labels to be configured and published in the M365 Compliance portal (or Office 365 Security and Compliance portal). If your sensitivity labels are deployed as part of the Classic platform in Azure, please ensure you are migrating to unified sensitivity labels as documented here.
