Microsoft 365: All June 2026 Updates

Microsoft 365 in June 2026: What's Changing for IT Teams

Each month, Microsoft publishes dozens of announcements covering its entire Microsoft 365 ecosystem. This article synthesizes the most significant developments from June 2026, organized by workload, to help you prioritize actions and anticipate impacts on your environments.

Microsoft Teams: New Telephony and Collaboration Features

Managing Multiple Phone Lines on Teams Mobile

Microsoft is extending multi-line support in Teams to the mobile application. A user with multiple assigned numbers can now switch between lines directly from the mobile interface before making a call. This functionality, already available on desktop, fills a notable gap for mobile professionals.

• Planned deployment: end of July, completion mid-August

Team Invitations Sent from the Sender's Address

Previously, invitations to Teams meetings sent to external guests came from a no-reply address, making follow-up and post-invitation collaboration difficult. Now these emails will be sent from the organizer's email address, improving clarity and facilitating direct exchanges from the recipient's mailbox.

• Planned deployment: end of June, completion end of July

Event Planning Through Delegation

Executive assistants and chiefs of staff who organize meetings on behalf of executives will now see these events appear as originating from the designated organizer's calendar (the CEO, for example), rather than from the delegate's calendar. This clarification is essential in enterprise environments where calendar management is centralized.

• Planned deployment: early July, completion end of July

Associating a Teams Meeting with an Existing Planner Plan

Each Teams meeting automatically created a new Planner plan, generating unwanted plan proliferation. It will now be possible to attach a meeting to an existing Planner plan, offering better task organization and reducing workspace fragmentation.

• Planned deployment: end of July, completion end of August

Automatic Recording and Transcription for Call Queues

Companies using Teams Phone with call queues functionality will be able to configure automatic recording and transcription of incoming calls. Today, each agent must manually trigger recording. This automation addresses common quality assurance and compliance needs.

• Planned deployment: early August, completion mid-August

---

Microsoft Outlook: Notification Grouping

Outlook on the web benefits from improved notification experience: when multiple emails arrive within a very short time interval, a single grouped notification is now displayed instead of a stack of successive toast notifications. This change reduces interruptions and improves user focus.

• Planned deployment: end of June, completion end of July

---

OneDrive and SharePoint: Storage and Archiving

New Dedicated Shortcuts Folder in OneDrive

An update to the OneDrive interface introduces a dedicated Shortcuts folder. Previously, shortcuts to shared files or folders were added to the root of the user's OneDrive, which could quickly become difficult to manage. This centralized folder improves navigation and accessibility to frequently used resources.

• Planned deployment: mid-July, completion end of July

Unification of OneDrive Domain

Microsoft is progressively transitioning to a unified domain for OneDrive links: onedrive.cloud.microsoft. The old format {tenant}-my.sharepoint.com will continue to work in parallel, ensuring continuity of existing links. This evolution is part of Microsoft 365's domain consolidation strategy.

• Planned deployment: early July, completion end of June 2026

Metered Billing for Additional SharePoint Storage

SharePoint is introducing a metered (pay-as-you-go) billing model for storage beyond the allocated quota. Previously, organizations had to purchase additional capacity blocks upfront. This new model offers greater flexibility, particularly for organizations with variable storage needs. The cost remains high — comparing with prepaid units is recommended before any commitment.

• Planned deployment: September 2025, completion October 2025

General Availability of Microsoft 365 Archiving Service

The Microsoft 365 Archiving service is moving to general availability. This complementary service, billed per gigabyte, allows archiving content at the file level (rather than just at the site level), placing it in a cold storage tier. Archived content remains discoverable via eDiscovery but no longer consumes the organization's SharePoint quota.

• Planned deployment: early July, completion end of July

Microsoft Entra: Enhanced Authentication and Device Governance

Conditional Access and Device Registration

Conditional access policies can now be applied during new device registration, requiring the user to previously have Windows Hello for Business or macOS Platform SSO as an authentication method. This evolution allows enforcing authentication strength requirements starting at the enrollment phase, filling an important gap in Entra Join scenarios.

• Deployment date: July 13, 2025 for all tenants

SSPR: Migration to Registered Authentication Methods

Microsoft SSPR (Self-Service Password Reset) previously accepted directory attributes (mobile number, email) as contact methods, even if they weren't formally registered by the user. Now these attributes must be validated through a registration campaign:

• July 6, 2025: beginning of user solicitation campaign
• September 7, 2025: beginning of enforcement — non-compliant users will no longer be able to use unvalidated directory attributes

Soft Delete of Entra Devices (Preview)

A new preview feature allows deleting an Entra device to a temporary deletion container (soft delete), recoverable for 30 days. This approach is particularly useful when it's necessary to retain access to BitLocker keys or LAPS passwords associated with a device before proceeding with permanent deletion.

Microsoft Edge: Browser Extension Monitoring via Edge Management Service

The Edge Management Service now integrates a console for monitoring browser extensions deployed across the organization. Administrators have centralized visibility into all active extensions, allowing identification of:

• Potentially malicious or unapproved extensions

• Missing mandatory security extensions (password manager, for example)

• Device compliance against a defined extension policy

• Deployment: mid-June 2025

---

Microsoft Copilot: Updates and Billing Models

Real-Time Screen Sharing in Copilot Voice Sessions

Users can now share their screen or desktop during a Copilot Voice session, allowing the assistant to answer contextual questions about displayed content, purely through voice. This feature offers a more guided experience than text input.

• Planned deployment: end of June, completion end of July

Creating PowerPoint Presentations with a Brand Kit

Copilot in PowerPoint now allows selecting or uploading a brand kit when generating content. The assistant automatically integrates the brand identity (colors, typography, logos) into generated presentations. A long-awaited feature for marketing and communications teams.

• Planned deployment: mid-June, completion end of June

Centralized Prompt Library in Copilot Chat

Microsoft 365 administrators can now manage a shared prompt library directly from the admin center. Users and department managers can submit validated prompts, accessible to all users in the Copilot Chat interface. This encourages standardization of usage and large-scale adoption.

• Planned deployment: early July, completion end of July

Copilot Cowork: General Availability and Metered Billing

Copilot Cowork (formerly Frontier early access) is now generally available. It's an autonomous agent capable of executing complex background tasks on your Microsoft 365 data.

WorkIQ API: General Availability

The WorkIQ API is now generally available. WorkIQ is Microsoft's framework that aggregates Microsoft Graph data to feed Copilot models with enriched context. Opening via API allows integrating this intelligence into third-party agents, MCP servers, or REST endpoints. This service also follows the metered billing model of Copilot Cowork.

Microsoft Scout: Autonomous Agent in Early Access

Microsoft Scout is an autonomous agent, comparable to Copilot Cowork, but designed to operate locally on the workstation. It can interact with Windows File Explorer and execute background tasks without manual intervention. Scout is available as part of the Frontier (early access) program and doesn't yet have a GA date. Its billing follows a separate model from Copilot Cowork and standard Microsoft 365 subscriptions.

Copilot Notebooks Available to Free Copilot Chat Users

A lite version of Copilot Notebooks is now accessible to users with only the free version of Copilot Chat. This allows organizations that haven't subscribed to a paid Copilot license to benefit from a basic grounding experience.

• Planned deployment: mid-June 2025

Copilot in Word: Advanced Change Tracking

Copilot in Word improves handling of complex edits: changes suggested by Copilot now appear via Word's native track changes feature, and it's possible to ask Copilot to insert comments directly in the document.

• Planned deployment: early June, completion early July

Copilot Notebooks: Integration of Outlook Emails as Grounding Source

Copilot Notebooks can now ingest Outlook emails as contextual source. This integration is particularly useful for professionals who want to anchor their analysis or document production in existing email exchanges (file tracking, client communications, etc.).

• Planned deployment: early July, completion end of July

Excel Agent: Explicit Grounding with External Documents

The Copilot in Excel agent now supports explicit grounding: it's possible to provide it with a Word document or another Excel workbook as a source of supplementary instructions, allowing the agent to contextualize its actions on the current workbook.

• Deployment: ongoing since April, completion expected end of June 2025

Microsoft 365 Administration: Defender, Intune, and Licenses

Defender for Cloud Apps: Governance Extended to Service Principals

The App Governance feature of Defender for Cloud Apps (available on enterprise plans or as an add-on) now extends its coverage to all service principals, not just those with explicit API permissions. This evolution improves detection of risky configurations, particularly when a service principal is assigned sensitive roles without associated API permission — a documented attack vector.

• Planned deployment: end of June, completion early July

Defender for Endpoint: Migration to Microsoft Update

Updates for the Defender for Endpoint platform (and Defender for Business) will now be distributed via the Microsoft Update channel (Windows Update), instead of OS security updates. This change aligns Defender for Endpoint behavior with that of other Defender components (antivirus, for example). No administrative action is required.

• Deployment: throughout 2025, completion in autumn

New Intune Features Included in Microsoft 365 E3 and E5

Announced in December 2024, the inclusion of additional Intune features in Microsoft 365 E3 and E5 plans becomes effective:

• July 1, 2025: effective date
• August 2025: complete visibility in eligible tenants

These additional features are included in your existing subscription at no additional cost.

New Microsoft 365 Business SKUs with Copilot

Microsoft is introducing combined SKUs of Microsoft 365 Business + Copilot at a price lower than purchasing the two subscriptions separately:

These new SKUs are available through CSP resellers (Pax8, Ingram, etc.).

• Planned deployment: end of June, completion early July

Agents 365: Minimum Requirements Raised to Microsoft 365 E5

The Agents 365 platform (centralized management of AI agents in an organization) now requires Microsoft 365 E5 license as a minimum requirement, due to increased security and compliance requirements for governing autonomous agents. This feature is also included in the new Microsoft 365 E7 plan.
