Co-authoring with MIP Encrypted Document

Read Time: 2 minutes

Co-authoring on Word, Excel, and PowerPoint document which are encrypted using Microsoft Information Protection (MIP) is now generally available.

This enhancement allows organizations various improvements, like the end-user productivity of collaboration on sensitive documents, or adding to their security posture overall, by encrypting a larger portion of their sensitive documents without restricting co-authoring.

Specifically, the change allows for MIP Protected files to be encrypted to specific end-users, while allowing them to edit the documents with their applications, as they would any other file.

Organizational Change Management

Co-authoring MIP encrypted files provides a benefit to the end-users, as such it should be communicated with them to understand how it is for their benefit, for the organization to realize the value of the feature.

For example, end-users can now share “need-to-know” files with specific individuals in an appropriate information repository, and collaborate on the document as they would any other document. They can rest assured their file is appropriately protected, while storing the file where it should reside, as opposed to using unauthorized or transitory workspaces such as OneDrive.

Technical Preparation

  1. Ensure Office has the latest updates deployed (either Current Channel or Monthly Enterprise Channel)
  2. Update any Azure Information Protection (AIP) unified labeling clients (version
  3. Enable the feature within the Compliance Center (Compliance Center)

    Getting Started with Sensitivity Labels for Files and Emails

    Read Time: 3 minutes

    All information is not equal.

    Some documents or emails have private financial or health information and others have plans for lunch.

    Sensitivity Labels within Microsoft 365 provides end-users the ability to classify their documents and emails to ensure a certain level of information protection to both their and the organization’s content.

    Sensitivity Labels for files and emails allow staff to identify specific documents as more or less sensitive than others.

    For example, a briefing note to senior leadership could be tagged as ‘confidential’, which would then add a “confidential” watermark added to the document and restrict it from being shared externally. Compliance officers would also be able to filter reports on documents marked as confidential.

    Applying labels is easy.

    Once Sensitivity Labels are created and published, individuals can choose to tag content directly within the application, providing them a seamless and low friction experience.

    Emails can be tagged with their “sensitivity” when being drafted, and documents anytime they are opened. These features are available in both the installed applications and online browser based versions.

    Sensitivity Labels allow individuals to mark files and emails with both different controls (e.g. allow internal access only) or using an existing information classification adopted or published by the organization (e.g. Protected A).

    Options for controls are:

    • restrict/provide access to appropriate roles (and individuals)
    • create a watermarks, header, and/or footer on the document to communicate the document’s sensitivity.

    Planning Sensitivity Labels

    When planning Sensitivity Labels, it is important to consider certain key factors to ensure successful implementation and adoption.

    • Align to existing information security classification schemas where available
    • Leverage a cross-functional team to build the label business and technical requirements
    • A clear and concise set of details will ensure labels are used correctly, rather than providing too many options with language requiring a reference guide or training course
    • Ensure alignment, approval from all key stakeholders (not just IT or Cybersecurity), Sensitivity Labels can mark documents (potentially impacting existing templates) and more importantly can effect the ability to collaborate (restricting documents to internal only or subsets of internal users).


    • Pilot the labels with a small group and collect feedback prior to implementation
    • If introduced into an active environment, consider a phased approach – avoid restricting access in bulk to focus on training and adoption, to build a cultural practice within the organization without impacting day-to-day activities
