Hierarchical organization of content with team sites, communication sites, and hub sites for modern intranets.
Document Libraries
Store, organize, and collaborate on documents with version history, metadata, and content types.
External Sharing
Control how content is shared with external partners — from anonymous links to domain-restricted sharing.
Permissions Management
Fine-grained access control at site, library, and item level using groups and permission levels.
Compliance & Retention
Retention labels, policies, and eDiscovery support for regulatory compliance and legal hold scenarios.
Search & Discovery
Powerful search capabilities with metadata tagging, content types, and managed properties for discovery.

⚡ Common Troubleshooting Scenario
Issue: A user reports “Access Denied” when opening a SharePoint site they need for their project.
1️⃣ Check site permissions — verify the user or their group is added to the site (Site Settings → Site Permissions)
2️⃣ Use “Check Permissions” on the site to see the user’s effective permission level
3️⃣ Verify group membership has propagated — Azure AD/M365 Group changes can take time to sync
4️⃣ Check for unique (broken) permission inheritance on the specific library or item
5️⃣ Confirm no Conditional Access or sensitivity label policy is blocking access from the user’s device/location
6️⃣ Review the site’s access requests list and audit logs for prior denied or removed access
