Microsoft 365 June 2025: Massive Updates, Surprising Retirements, and Copilot AI Empower Users Worldwide

Microsoft 365 continues to lead the way with powerful productivity tools and cloud-based solutions for businesses of all sizes. June 2025 marks a pivotal month for Microsoft 365 users, with a suite of new features, significant product retirements, and game-changing Copilot AI enhancements rolling out across the ecosystem. Here’s a comprehensive look at what’s new, what’s changing, and what your organization needs to do to stay ahead.

Microsoft 365 June 2025 Updates

1. OneDrive: Streamlined File Ownership Transfers

Managing data when employees leave an organization has always been a challenge. Microsoft 365 June 2025 updates introduce a more efficient process for transferring file ownership in OneDrive. Admins now benefit from:

1. Improved Cleanup Notifications: Receive clearer alerts when files need to be transitioned.

2. Essential File Filters: Quickly identify and prioritize business-critical files.

3. “Move and Keep Sharing” Option: Transfer files while maintaining existing sharing permissions, ensuring ongoing collaboration without disruption.

This OneDrive update streamlines offboarding and minimizes data loss, making it easier for IT teams to manage user transitions.

2. Outlook: Shared Mailbox Support and Copilot Integration

The new Outlook for Windows has taken a significant leap forward. Users can now add shared mailboxes as accounts, providing a seamless and integrated experience for teams that rely on shared communications1. This long-requested feature simplifies collaboration and centralizes email management.

Copilot for Outlook also sees major improvements:

1. Ask Copilot on Meeting Recordings: Select a meeting recording in OneDrive and ask Copilot to summarize, highlight mentions, and recommend action items. This is available to commercial customers with a Copilot for Microsoft 365 license.

2. Schedule from Email: Copilot can convert an email thread into a meeting invite, generating the title, agenda, summary, and attendee list automatically. This feature works across new Outlook for Windows, web, Mac, and mobile platforms.

3. Copilot Admin Controls: IT administrators can now manage Copilot agents directly from the Microsoft 365 Admin Center, including approval flows and inventory management.

These updates reinforce Microsoft’s commitment to AI-powered productivity and smarter communication.

3. SharePoint: Flexible Layouts, eSignature, and Read Time

SharePoint authors now have more creative freedom with the launch of flexible layouts. Web parts can be moved and resized outside traditional column structures, allowing for more dynamic and engaging pages.

• SharePoint eSignature for Word: Now available for tenants with Word clients on the Current Channel, streamlining document signing workflows and reducing reliance on third-party solutions.

• Estimated Read Time: Soon, SharePoint News posts will display estimated read times, helping readers manage their workload and prioritize content.

These enhancements make SharePoint an even more powerful platform for communication and collaboration.

4. Teams and SharePoint: Workflow Automation Simplified

A new Workflows app is rolling out to Teams and SharePoint, empowering users to automate tasks in three steps or less. Everyday users can now create automations without needing advanced technical skills, making it easier to boost productivity and streamline repetitive processes.

Microsoft 365 Retirements June 2025

Change is inevitable in the cloud, and Microsoft is retiring several legacy features and products to pave the way for innovation.

1. OneNote Meeting Details Feature

The Meeting Details feature in OneNote for Windows 10 is being retired starting June 2025. Users are encouraged to explore alternative methods for integrating meeting information into their notes1.

2. Viva Engage “Private Content Mode”

Viva Engage’s “Private Content Mode” will be discontinued by June 30, 2025. Organizations should transition to modernized external networks to continue secure and compliant collaboration1.

3. Teams Recording Initiator Policy

The MeetingInitiator value and MeetingRecordingOwnership setting are being retired by June 30, 2025. This impacts how meeting recordings are managed, requiring organizations to review their Teams recording policies and make necessary adjustments1.

4. Outlook Sports Calendar (Interesting Calendars)

The “Interesting Calendars” feature, which allowed users to subscribe to sports schedules, is being phased out in early June 2025. Users will need to seek alternative calendar integrations for similar functionality.

5. Non-Profit Grant Offers

Microsoft is ending Business Premium and Office 365 E1 grant offers for non-profit organizations. Non-profits should review their licensing and explore other Microsoft offerings to ensure continued access to essential tools1.

Security, Compliance, and Administration Updates

1. SharePoint Online CDN Migration

SharePoint Online assets are migrating to a new Content Delivery Network (CDN). Admins must update configurations to allow the new CDN domain and avoid using hardcoded links, ensuring uninterrupted access to assets.

2. Teams DLP Incident Reports

Teams Data Loss Prevention (DLP) incident report emails will now be sent from a new address. Admins should update their email filters to ensure these critical alerts are not missed.

3. Exchange and Mailbox Audit Cmdlet Changes

Exchange Online is updating its cmdlets to restrict the data returned and make some audit log cmdlets read-only, strengthening security and compliance across the platform.

4. DLP Policy Configuration Enhancements

Admins can now independently configure email notifications and policy tips for SharePoint and OneDrive DLP policies. This provides greater flexibility and control over data protection strategies.

What’s Next on the Microsoft 365 Roadmap?

Looking ahead, Microsoft is preparing even more improvements for its productivity suite:

• Teams Copilot Enhancements: Soon, Copilot in Teams meetings will be able to search both the web and internal work files, emails, and people, providing richer, more insightful responses.

• Microsoft Purview Compliance Updates: New options for managing Copilot retention policies separately from Teams chats, along with enhanced information barriers for large organizations, are on the horizon.

Action Items for Organizations

With so many changes happening in June 2025, organizations should:

• Review and Transition from Retiring Features: Plan migrations away from features like Classic Teams, SharePoint Alerts, and OneNote Meeting Details.

• Upgrade to Supported Versions: Ensure all users are on supported Microsoft 365 Apps and operating systems before October 2025 to avoid disruptions.
