As we move into 2025, Microsoft 365 is poised for several transformative changes that will redefine how organizations manage data, security, and collaboration. The roadmap for this year includes significant updates, retirements, and future developments that will shape the platform in the coming years. Here’s what’s coming, going, and changing in Microsoft 365 and what organizations should prepare for as they adapt to the evolving digital landscape.
1. Retirement of Classic Teams Desktop App
By July 1, 2025, Microsoft will retire the classic Teams desktop app, urging users to transition to the newer, faster version. This updated Teams app offers improved speed and a more integrated experience across the Microsoft 365 ecosystem, streamlining workflows and fostering better collaboration.
2. Future Developments: Microsoft 365 Backup with Long-Term Retention
Looking beyond 2025, Microsoft has already planned a key enhancement in data retention with the introduction of long-term retention periods for M365 backups. Although still in development, this feature is expected to enter preview in March 2026 and begin rolling out by August 2026. This will be critical for businesses requiring extended retention policies for data compliance and governance.
3. End of Support for Office 2016 and Office 2019
Support for Office 2016 and Office 2019 ends on October 14, 2025, marking the end of security patches and updates for these versions. Organizations that continue using these apps post-support may face security vulnerabilities, making it essential to transition to Microsoft 365 Apps to ensure ongoing protection and access to the latest features. EdbMails Office 365 Migration Software simplifies the transition by allowing seamless data migration from legacy Office versions to Microsoft 365. Whether you’re moving emails, calendars, contacts, or entire mailboxes, EdbMails ensures secure and efficient migrations without data loss or downtime.
4. Farewell to Viva Topics and Viva Goals
Microsoft is retiring Viva Topics in February 2025 and Viva Goals by December 2025. As part of this shift, Microsoft is focusing on integrating AI-powered knowledge management through tools like Microsoft Copilot, enabling businesses to embrace more intuitive AI-driven solutions for managing information and goals.
5. Microsoft Viva: Import HRIS Data into Viva Glint
Organizations using Microsoft Viva can expect a key enhancement by January 2026, as the platform will introduce functionality to import HRIS data into Viva Glint from the Microsoft Admin Center. This update will simplify the integration of HR data for performance management and employee engagement analytics.
6. Strengthening Security with Zero-Trust Architecture
As the threat landscape evolves, Microsoft 365 will continue enhancing its zero-trust architecture and security protocols to protect against cyber threats. With stronger threat detection, encryption, and secure access controls, businesses will have the tools needed to protect sensitive data and maintain compliance with security regulations.
7. Transition from OneNote for Windows 10
OneNote for Windows 10 will be retired in October 2025, making way for the more feature-rich OneNote app available in Microsoft 365. This change will enable users to leverage enhanced productivity features, deeper integrations, and more seamless note-taking experiences.
8. Microsoft Intune: Enhanced Hardware-Backed Attestation for Windows 11
On the security front, Microsoft Intune will feature enhanced hardware-backed attestation for Windows 11 devices starting in December 2025. This enhancement will provide stronger protection for device integrity and security, ensuring that only trusted hardware and software are allowed to access organizational resources.
9. AI-Driven Personalization and User Experience
AI and machine learning will continue to play a larger role in Microsoft 365 by automating daily tasks and offering a more personalized user experience. These enhancements will help users become more productive with tools that tailor to individual work habits, further driving efficiency across organizations.
10. Expansion of Cloud Services and Collaboration Tools
Microsoft 365’s cloud services will see continued expansion in terms of storage, scalability, and collaboration capabilities. Tools like SharePoint and OneDrive will be improved to make teamwork more seamless, especially in hybrid and remote work environments.
11. Accessibility and Inclusivity Advancements
Microsoft 365 will further its focus on inclusivity by introducing more accessibility features that cater to users of all abilities. Expect enhancements in screen reader functionality, voice control, and assistive technology, ensuring the platform is more inclusive than ever.
12. SharePoint: Archive File-Level Archiving
Another important development for SharePoint users is the planned introduction of file-level archiving within the Microsoft 365 Archive. Set to enter preview by January 2026, with a full rollout starting in July 2026, this feature will provide organizations with more granular control over archiving and data retention.
13. OneNote Mobile Productivity Boost with Voice and Copilot
For OneNote mobile users on Android, 2026 will bring a significant productivity enhancement with voice-powered features via Copilot. This will allow users to dictate notes and automate workflows, offering a more intuitive and hands-free experience. The feature is scheduled for preview in June 2026, with a rollout occurring the same month.
