With hybrid work here to stay, organizations are increasingly looking for ways to facilitate seamless collaboration among workgroups and across organizations while keeping their data secure and compliant.


At Microsoft, we have been working hard to introduce product innovations to help organizations achieve this. Today – we are excited to announce co-authoring on Microsoft Information Protection (MIP) encrypted documents is now coming to mobile for both Android and iOS.


Customers will no longer be locked out of these documents on a mobile device which means greater flexibility to choose your device for being productive on the go. This expands upon our current co-authoring support for desktops Windows and Mac and Office on the web.

Multi-platform collaborative co-authoring is an essential component of MIP.  As an intelligent, unified, and extensible solution to protect sensitive data across your enterprise – in Microsoft 365 cloud services, on-premises, third-party SaaS applications, and more, MIP provides a unified set of capabilities to know your data, protect your data, and help prevent data loss across Microsoft 365 apps (e.g., Word, PowerPoint, Excel, Outlook) and services (e.g., Microsoft Teams, SharePoint, and Exchange).
