Microsoft is retiring One-Time Passcode (SPO OTP) authentication and transitioning to Entra B2B guest accounts for external users. This ensures that SharePoint and OneDrive external collaboration is governed by the same security and compliance standards as internal access. SPO OTP method will be fully retired by August 31, 2026, following rollout beginning in May 2026.
Microsoft now allows admins to enforce a default expiration period for “People in your organization” sharing links in SharePoint Online and OneDrive. By configuring maximum and recommended expiration values, admins can prevent internal links from staying active indefinitely. This update helps reduce stale access while maintaining flexible and secure collaboration.
Starting March 3, 2026, Microsoft is introducing a completely reimagined SharePoint experience in Microsoft 365, designed to make collaboration smarter, faster, and more intuitive. The new experience features a redesigned app bar categorized into three core jobs - Discover, Publish, and Build along with AI-powered tools and a neutral theme.
Microsoft Entra Kerberos provides a simpler way to set up hybrid-joined devices by reducing the need for Microsoft Entra Connect or Active Directory Federation Services. By using cloud-based authentication with Microsoft Entra ID, organizations can streamline device onboarding and simplify hybrid deployments.
Tracking Microsoft 365 licenses can be challenging for many organizations. To simplify this, Microsoft introduced the Cloud Licensing beta API in Microsoft Graph (preview), giving admins and developers granular control. Instead of just showing a flat license count, it supports batch tracking, queuing users when licenses run out, and quickly identifying assignment errors.
Starting in late February 2026, Microsoft Teams Mobile (Android & iOS) will prompt users to choose between Edge and the default browser when opening non-Office and PDF links. While Microsoft presents this as a usability update, the flow clearly promotes Edge within the decision screen. It’s less forceful than before, but still a built-in nudge toward Microsoft’s browser. The feature is enabled by default for all tenants but can be disabled by admins via PowerShell.
