Updated May 15, 2026: We have updated the timeline. Thank you for your patience. We're introducing more flexible and precise audience targeting in Viva Engage, starting with Storyline Announcements. This update allows leaders and their delegates to define a custom audience at the time of posting—without relying on pre-configured Leader Audiences. Audiences can include organizational attributes (such as reporting structure, country, department, job title), existing groups (Microsoft 365 Groups, DLs, SGs), or individual users by name. This flexibility enables more timely, targeted communication, helping leaders reach the right people with the right message.

This feature is ideal for leaders who want to tailor communicati

Updated May 15, 2026: We have updated the timeline. Thank you for your patience. [Introduction:] We’re introducing a simpler way to view conversations in Viva Engage communities, organized by recent posts rather than recent activity.

This message is associated with Microsoft 365 Roadmap ID 513275. [When this will happen:] General Availability (Worldwide): We will begin rolling out in July 2026 (previously May). [How this will affect your organization:]This change should align better with how people expect to browse and engage with content in their communities, while still preserving the triage flow for those who prefer it. Who is affected: All Viva Engage users

Updated May 13, 2026: We have initiated the deprecation rollout and expect to reach 100% production coverage in the next few weeks. We strongly recommend that customers transition to modern authentication at the earliest opportunity. Thank you for your patience. [Introduction:] As part of the Microsoft Secure Future Initiative (SFI) and in alignment with the “Secure by Default” principle, we’re retiring the legacy IDCRL (Identity Client Run Time Library) authentication protocol in SharePoint Online and OneDrive for Business. This change helps strengthen your organization’s security posture by enforcing modern authentication standards—OpenID Connect and OAuth—which reduce exposure to outdated and vulnerable authentication methods. [When this will happen:] Starting February 16, 2026: Legacy client authentication will be blocked by default. Organizations may temporarily re-enable it using P
