SharePoint Online Storage Limits

SharePoint Online, Microsoft's cloud-based collaboration and document management platform, offers robust storage capabilities. However, it's essential to understand its limits to optimize usage and prevent potential issues. Let's delve into the intricacies of SharePoint Online storage limits.

Microsoft continually updates its service to accommodate growing user needs, but knowing the current limits helps in planning and efficient use of resources. Let's explore the key aspects of SharePoint Online storage and associated limits.

SharePoint Online Tenant Storage Limit

At the highest level, SharePoint Online has a tenant storage limit. This cap applies to the entire SharePoint Online environment within your organization. The current limit is 25 TB per tenant.

It's crucial to note that this limit is soft, meaning it provides an upper boundary, but Microsoft will not charge you for exceeding it. However, it's a good practice to stay within this limit or close to it to ensure optimal service performance.

SharePoint Site Quota

Within the tenant, sites have their own storage quotas. The personal site (OneDrive for Business) storage quota is 25 TB per user, while team site and communication site quotas are 250 GB each. Conversely, migration and record centers do not have a quota limit.

Pro tip: You can adjust site storage quotas to control how much space sites can consume. It's recommended to set these limits for better resource management.

Subscription-Based Storage Limits

Certain Microsoft 365 subscriptions come with specific amounts of OneDrive storage space. For instance, Microsoft 365 Business Basic offers 1 TB, while Microsoft 365 Business Standard provides 1 TB per user. Enterprise licenses, such as E1 and E3, offer unlimited OneDrive storage.

Pay special attention to these limits, especially if your organization uses services like OneDrive for Business, which shares the same storage pool as SharePoint Online.

SharePoint File Size Limitations

While SharePoint Online offers significant storage, it also enforces a file size limit. The current limit is 250 GB per individual file and 250 GB for folder sizes. This limit applies to uploading, descending, and moving files.

It's vital to be aware of this restriction, particularly when dealing with large files or folders. In such cases, consider breaking down large files into smaller, manageable components or using third-party tools specifically designed to handle large file sizes.

Deployment Size Limitations

SharePoint Online also has deployment-specific size limits. For instance, the maximum list item size is 250 MB, including attachments. The maximum response size, including headers, is 12 MB. Maximum item counts vary per list type, ranging from 5,000 to 30,000,000 items.

These limits are crucial for maintaining performance and efficiency within your SharePoint environment. Being mindful of these boundaries allows you to plan accordingly and avoid encountering unexpected challenges.

Balancing storage limits and performance is a delicate task. However, with a solid understanding of SharePoint Online's storage limits, you're well-equipped to manage and optimize your organization's SharePoint environment effectively. Regularly review and adapt your practices to accommodate evolving limits and ensure optimal service performance.
