SharePoint Tips: Set Default Storage Limits for New Sites Easily

Key insights

• Default Storage Limit for new SharePoint sites can now be set directly in the SharePoint Admin Center, affecting all new sites made from the SharePoint Home page, Microsoft Teams, or Active Sites.
  
• The Site Creation settings allow admins to choose a default storage limit between 1 GB and 25,600 GB (25 TB) for any newly created site, giving more control over storage use.
  
• Previously, only sites created in the SharePoint Admin Center were affected by manual storage settings; now, this applies to all new sites regardless of how they are created.
  
• The default value often displays as 25 TB (the maximum allowed per site), but most new sites—especially those made via Teams or SharePoint—start with a 1 TB quota unless changed.
  
• Admins can override individual site storage limits after creation using the SharePoint Admin Center or PowerShell, making it easy to adjust quotas as needed.
  
• This update helps organizations improve storage governance, prevents unexpected large allocations, and ensures better use of overall tenant storage resources.

Introduction: New SharePoint Storage Limit Controls Explained

In a recent YouTube video by Ami Diamond [MVP], viewers are introduced to a significant update in how organizations manage storage for new SharePoint sites. Previously, storage limits were only adjustable for sites created directly through the SharePoint Admin Center. However, Microsoft has now released an improvement that extends this control to all new sites, including those created via Microsoft Teams and the SharePoint Home page. This enhancement aims to simplify storage management while giving administrators greater oversight.

The change, though seemingly minor, can have a substantial impact on how organizations govern their storage resources. By consolidating default storage settings under one roof, Microsoft seeks to address previous inconsistencies and streamline the site creation process for IT teams.

Understanding the Previous Approach to Storage Limits

Until recently, setting storage limits for SharePoint sites was a fragmented experience. Administrators could navigate to the SharePoint Admin Center, find the Site storage limits under Settings, and switch between Automatic or Manual allocation. This allowed for some flexibility, but only for sites spun up directly from the Admin Center interface.

Sites created by end users through channels like Teams or the SharePoint Home page were not governed by these settings. Instead, they would automatically receive a hefty 25TB storage allocation by default. This default, while reflecting Microsoft's upper limit for a single site, did not always align with organizational needs or storage policies, potentially leading to inefficient resource use.

The New Default Storage Limit Feature

Now, Microsoft has introduced a dedicated option to set the default storage limit for new SharePoint sites within the Site Creation settings of the Admin Center. This adjustment applies across all entry points—whether sites are created from Teams, SharePoint Home, or Active Sites.

Administrators can access this feature by navigating to the SharePoint Admin Center, expanding the Sites menu, and selecting Active sites. Under Settings, they will now find the ability to specify a default storage value for newly created sites, ranging from 1 GB to 25,600 GB (25 TB). Once adjusted, this setting ensures all new sites are assigned an appropriate quota from the outset, aligning with company policies and storage strategies.

Implications for Storage Governance

This update delivers important benefits for storage governance. By offering a single, centralized place to manage default site storage, organizations can prevent unintended over-allocation of resources. It also reduces the risk of storage shortages caused by unchecked site growth, which can impact overall tenant performance and cost.

However, balancing flexibility and control remains a challenge. While the default setting streamlines initial allocations, administrators must still monitor actual usage and adjust quotas as business needs evolve. Fortunately, SharePoint provides tools for overriding individual site limits post-creation, either through the Admin Center or via PowerShell commands.

Tradeoffs and Challenges

The consolidation of default storage limits presents both opportunities and tradeoffs. On one hand, it simplifies the administrator’s workflow and supports better planning. On the other hand, setting a universal default may not fit every team’s requirements, especially in large organizations with diverse project needs. There is also the ongoing challenge of educating end users about these changes and ensuring that storage requests are handled efficiently.

Moreover, the total available storage for an organization is still governed by its Microsoft 365 subscription and licenses. Therefore, IT departments must keep a close eye on overall storage consumption, adjusting the default as needed to avoid hitting tenant-wide limits.

Conclusion: A Step Forward in SharePoint Management

In summary, the new default storage limit setting in SharePoint represents a meaningful advance in storage governance. By unifying control across all site creation methods, Microsoft makes it easier for administrators to enforce organizational policies and optimize resource allocation.

As with any administrative update, success will depend on thoughtful configuration and ongoing oversight. Organizations should review their current storage needs, communicate changes to stakeholders, and be prepared to fine-tune settings as usage patterns shift. With these measures in place, this new capability promises to streamline SharePoint management well into the future.
