Top 10 Microsoft 365 Admin Tasks for 2025
The 10 most important Microsoft 365 admin tasks to focus on in 2025 — from security baselines to AI readiness.
Managing Microsoft 365 in 2025 is no longer just about uptime. It’s about enabling productivity, safeguarding data, and preparing for AI-driven work. Whether you’re an MSP, IT admin, or consultant, these are the 10 admin tasks you cannot afford to miss this year:
1. Apply Entra ID Conditional Access Baselines
Every tenant needs strong identity governance. Start with MFA for all users and condition-based policies.
2. Secure SharePoint & OneDrive Sharing
Review external sharing defaults, guest access, and expiration policies.
3. Enable Microsoft 365 Backup Coverage
Native retention ≠ backup. Make sure critical data is protected.
4. Review Data Classification & Sensitivity Labels
Protect your intellectual property with built-in classification tools.
5. Implement Endpoint Management with Intune
Zero-trust requires managed devices. Start with compliance baselines.
6. Turn on Audit & Compliance Logging
If it’s not logged, it didn’t happen. Verify audit policies in Purview.
7. Prepare for Copilot Readiness
Copilot thrives on high-quality, well-secured data. Clean up permissions.
8. Use Teams Lifecycle Policies
Archive inactive Teams, apply expiration, and enforce naming policies.
9. Automate License Management
Dynamic groups + automated provisioning = time saved, errors reduced.
10. Run Quarterly Security Reviews
Make it a habit: quarterly reviews of risk reports, shadow IT, and admin roles.
