3. Regularly Review Service Level Agreements (SLAs): Understand the commitments and compensations outlined by service providers in the event of outages.
4. Stay Informed: Monitor service status pages and subscribe to updates from providers to receive timely information about potential issues.
Conclusion
The January 22, 2026, Microsoft 365 outage serves as a reminder of the vulnerabilities inherent in cloud-based services. While Microsoft is actively working to resolve the issue and restore services, businesses must proactively prepare for such incidents to maintain operational resilience.
