Sensitivity labels now in Microsoft 365 web apps

Microsoft is rolling out a long-overdue change to the browser-based versions of Word, Excel, and PowerPoint: you can now apply sensitivity labels with user-defined permissions directly in the web apps without switching to the desktop client. Sensitivity labels are classification tags you attach to a file to control who can read, edit, or print it. They are configured centrally in Microsoft Purview (Microsoft's compliance and information protection platform) and enforced by the Rights Management Service (RMS), which is the encryption engine built into Microsoft 365. This update started rolling out in mid-April 2026 and is expected to be completed worldwide by early May 2026. It requires enabling coauthoring on encrypted files in your tenant beforehand.

Microsoft 365 Copilot Cowork moves beyond chat-based AI responses by acting as an autonomous agent—an AI that can perform multi-step tasks on your behalf across Outlook, Teams, Word, Excel, and other Microsoft 365 services. Cowork is built on top of Work IQ, Microsoft's intelligence layer that reads your emails, meetings, files, and organizational data to provide context for actions. As of May 2026, Cowork is available through the Frontier preview program and has expanded to include mobile support, custom skills, plugins, and integration with Agent 365. Access requires a Microsoft 365 Copilot license and enrollment in the Frontier early-access program.

This article explains what the report shows, how to access it, and what steps to take for each scenario.

Mail-Advanced.ReadWrite permissions required to change sensitive email properties in Exchange Online via Graph API

Mail-Advanced.ReadWrite allows you to modify sensitive properties in Exchange Online
Microsoft announced a breaking change to the Microsoft Graph API affecting Exchange Online: from December 31, 2026, applications that modify sensitive email properties -- such as the subject, body, or recipients -- on delivered messages must hold elevated Mail-Advanced.ReadWrite permissions. Until now, the standard Mail.ReadWrite permission was sufficient for these operations. The new permissions require explicit approval from the tenant administrator ("admin consent"). If you operate Microsoft 365 and have custom applications or third-party tools that interact with email via the Graph API, you need to audit and potentially update these apps before the enforcement date.

Policy-based automation for automatic archiving is planned for late 2026.

Exchange Web Services retirement in Exchange Online: timeline and migration to Microsoft Graph API

Exchange Web Services retirement timeline (image Microsoft)
Microsoft is retiring Exchange Web Services (EWS) in Exchange Online, with a phased shutdown beginning October 1, 2026, and complete retirement by April 1, 2027. You must migrate your applications to the Microsoft Graph API before the final deadline to maintain access to Exchange Online mailboxes. This retirement only affects Exchange Online in Microsoft 365 environments and does not impact on-premises Exchange Server installations. Organizations using EWS-dependent applications face service interruptions unless they transition to supported alternatives. The nearly 20-year-old protocol no longer meets modern security, scale, and reliability requirements.
