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.
