What Is the SharePoint Admin Center?
The SharePoint Admin Center (also known as the SharePoint Online Admin Center or SharePoint Management Console) is a centralized web-based management portal within Microsoft 365 that provides administrators with complete control over SharePoint Online settings, sites, policies, and tenant-wide configurations.

Sharing Policies
Configure organization-wide and site-level sharing and access policies
Storage Quotas
Monitor and manage storage allocation across all SharePoint sites
Security Controls
Implement access controls, compliance policies, and security settings
How to Access SharePoint Admin Center
There are several ways to access the SharePoint Admin Center. You'll need SharePoint Administrator or Global Administrator privileges in Microsoft 365.
Method 1: Direct URL Access
Navigate directly to your SharePoint Admin Center using this URL format:
Replace [your-tenant-name] with your organization's Microsoft 365 tenant name. For example, if your SharePoint URL is contoso.sharepoint.com, your admin center is at contoso-admin.sharepoint.com.
Method 2: Via Microsoft 365 Admin Center
- Sign in to admin.microsoft.com
- In the left navigation, expand "Admin centers"
- Click "SharePoint"
Method 3: Via Microsoft 365 App Launcher

Hub Sites
Hub sites provide a way to organize related sites and enable:
- Shared navigation across associated sites
- Consistent branding and theming
- Cross-site search aggregation
- News roll-up from associated sites
Sharing and Access Control Configuration
One of the most critical aspects of SharePoint administration is configuring sharing policies to balance collaboration with security.
Organization-Level Sharing Settings
Navigate to Policies → Sharing to configure:
| Sharing Level | Description | Use Case |
|---|---|---|
| Anyone | Anonymous links - no sign-in required | Public content, marketing materials |
| New and existing guests | External users must sign in or verify email | Partner collaboration, vendors |
| Existing guests only | Only guests already in your directory | Controlled external access |
| Only people in your organization | No external sharing allowed | Highly sensitive content |
Link Settings
- Default link type: Specific people, Organization, or Anyone
- Default permissions: View only or Edit
- Link expiration: Automatic expiry (1-730 days)
- Link permissions: Block downloads for view-only links
Storage Management
SharePoint Online provides pooled storage based on your license count. Effective storage management ensures optimal performance and cost control.
Understanding Storage Allocation
- Base storage: 1 TB per organization
- Per-user storage: 10 GB per licensed user
- Example: 100 users = 1 TB + (100 × 10 GB) = 2 TB total
Storage Management Best Practices
- Monitor regularly: Review storage reports monthly
- Set site quotas: Prevent individual sites from consuming excessive storage
- Configure version limits: Limit version history (100-500 versions typically sufficient)
- Implement retention policies: Auto-delete old content per compliance requirements
- Use Storage Metrics reports: Identify large files and libraries
Security and Compliance Settings
The SharePoint Admin Center integrates with Microsoft 365's security and compliance features to protect your organization's data.
Access Control Policies
- Unmanaged devices: Block or limit access from personal devices
- Network location: Restrict access to specific IP ranges
- Idle session timeout: Automatically sign out inactive users
- Conditional Access: Integration with Azure AD policies
Data Loss Prevention (DLP)
Configure DLP policies to prevent sensitive information from being shared inappropriately:
- Detect credit card numbers, SSNs, and other sensitive data types
- Block sharing of content matching DLP rules
- Generate alerts and reports for policy violations
Information Rights Management (IRM)
Enable IRM to protect documents with encryption and access restrictions even after download.
Migration Settings
The SharePoint Admin Center includes the Migration Center for moving content to SharePoint Online:
- SharePoint Migration Tool (SPMT): Migrate from on-premises SharePoint or file shares
- Migration Manager: Cloud-based migration for large-scale projects
- Mover: Migrate from other cloud providers (Google Drive, Box, Dropbox)
SharePoint Admin Center Best Practices
Enterprise Best Practice
Implement a hub site architecture to organize related sites and enable consistent navigation, search, and branding across your SharePoint environment. This significantly improves user adoption and content discoverability.
Governance Framework
- Site provisioning policies: Define who can create sites and which templates to use
- Naming conventions: Establish consistent naming for sites, groups, and URLs
- Lifecycle management: Set policies for inactive site archival or deletion
- Sensitivity labels: Apply Microsoft Purview sensitivity labels to classify sites
- Regular audits: Review permissions, external sharing, and compliance quarterly
Performance Optimization
- Enable CDN: Use Office 365 CDN for faster content delivery
- Optimize large lists: Create indexed columns, use filtered views
- Information architecture: Plan site hierarchy and navigation carefully
- Modern pages: Use modern SharePoint pages for better performance
Troubleshooting Common Issues
Storage Exceeded
Solution: Increase site quota, implement retention policies, or delete old versions and recycle bin items.
OneDrive Sync Issues
Solution: Check sync client version, verify site permissions, ensure path lengths under 400 characters.
Permission Errors
Solution: Verify user licenses, check Azure AD group memberships, review site permission inheritance.
External Sharing Blocked
Solution: Check tenant-level and site-level sharing policies. Site settings cannot be more permissive than tenant settings.
Site Not Appearing in Admin Center
Solution: Wait up to 24 hours for new sites to appear. Check if site was deleted (check Deleted sites).
Frequently Asked Questions
What is the URL for SharePoint Admin Center?
The SharePoint Admin Center URL follows the format: https://[tenant]-admin.sharepoint.com. Replace [tenant] with your organization's Microsoft 365 tenant name. You can also access it through the Microsoft 365 Admin Center under "Admin centers" → "SharePoint".
Who can access the SharePoint Admin Center?
Users with Global Administrator, SharePoint Administrator, or Global Reader (read-only) roles can access the SharePoint Admin Center. Regular users and site owners cannot access the tenant-level admin center.
What's the difference between SharePoint Admin Center and Site Settings?
The SharePoint Admin Center is for tenant-wide administration (all sites, organization policies, storage). Site Settings is for managing individual site configuration (permissions, features, design). Site owners access Site Settings; only admins access the Admin Center.
How do I recover a deleted SharePoint site?
Deleted sites go to the Deleted sites page in SharePoint Admin Center and are retained for 93 days. Navigate to Sites → Deleted sites, select the site, and click "Restore". After 93 days, sites are permanently deleted.
Can I manage SharePoint Server (on-premises) from SharePoint Admin Center?
No. The SharePoint Admin Center only manages SharePoint Online (Microsoft 365). SharePoint Server (on-premises) is managed through SharePoint Central Administration on your server. Hybrid configurations can connect the two environments.
How do I enable external sharing for a specific site?
Go to Active sites, select the site, click the "..." menu, then "Sharing". You can set sharing to be more restrictive than the tenant level but not more permissive. To enable broader sharing, first adjust tenant-level settings under Policies → Sharing.
