RMS Sharing
RMS Sharing (Rights Management Services Sharing) is a macOS component that enables Microsoft Office applications to enforce document protection and rights management policies. It handles encryption, access control, and expiration of shared documents within Microsoft 365 environments. The component is installed automatically when you set up Microsoft Office 2016 or later on macOS and works in the background to apply information protection rules, particularly for organizations using Azure Information Protection. Most individual users and organizations rely on this for securing sensitive documents before sharing them within corporate environments.
AI Recommendation
1 suggestionRMS Sharing is not a standalone application — it is a system component installed by Microsoft Office to handle document encryption and rights management on behalf of Word, Excel, PowerPoint and other Office apps. There is nothing to update separately. To ensure you have the latest version with native Apple Silicon support, update Microsoft Office itself to the latest version: launch Word or Excel, go to Help → Check for Updates, and let Microsoft AutoUpdate install the current Office build. If Office was originally installed via the Mac App Store, update through the App Store instead. Microsoft has shipped native Apple Silicon builds of Office since 2020, so updating to the latest version will bring RMS Sharing to native as well.
