Fix Teams Storage Report Does Not Match SharePoint for a Newly Created Team

When you create a new team in Microsoft Teams, the storage report in the Teams admin center can show a different number than what SharePoint reports for the connected site. This mismatch confuses admins who expect the numbers to be identical. The difference happens because Teams counts the entire site collection, including system data and the Teams data folder, while SharePoint may show only the document library. This article explains the root cause of the discrepancy and gives you clear steps to verify and reconcile the storage numbers.

You will learn how to check the actual storage usage in SharePoint, how to identify the hidden system folders that Teams counts, and how to make your reports consistent. The fix involves using the SharePoint admin center and the Get-SPOSite PowerShell cmdlet to get accurate numbers. By the end, you can confidently explain why the reports differ and how to get a true picture of your storage.

Why Teams Storage Report Differs from SharePoint for a New Team

When you create a new team, Teams automatically provisions a SharePoint site collection. This site collection contains a document library named “Documents” and several hidden system folders, such as the “Teams” folder that stores channel messages and files. The Teams admin center storage report sums the total storage used by the entire site collection, including these hidden folders and other system artifacts like the Site Pages library and the Site Assets library.

The Role of the Teams Data Folder

The “Teams” folder inside the site collection is where Teams stores all channel data, including chat files, wiki content, and meeting recordings. This folder is not visible in the default document library view, but it consumes storage. When you compare the Teams storage report to the SharePoint document library, you see a smaller number because SharePoint’s default view only shows the “Documents” library. The difference is often small for a new team, but it can grow as users add files to channels.

System Libraries and Site Collection Overhead

SharePoint site collections include system libraries like “Site Pages,” “Site Assets,” and the “Form” library. These libraries are part of the site collection and count toward the storage quota. The Teams admin center includes these in its report, while the SharePoint “Storage Metrics” page may exclude them depending on the view. This is why the numbers never match exactly, even for a brand-new team with no user-uploaded files.

Steps to Verify the Actual Storage Usage for a New Team

To reconcile the reports, you need to get the storage number directly from SharePoint. Use the following steps to check the site collection usage in two ways: through the SharePoint admin center and through PowerShell.

1. Open the SharePoint admin center
   Go to admin.microsoft.com and sign in as a SharePoint admin. In the left navigation, select SharePoint to open the SharePoint admin center.
2. Locate the site collection for your team
   In the SharePoint admin center, select Active sites from the left menu. Find the site whose URL matches your team’s SharePoint site. The site URL is typically https://yourtenant.sharepoint.com/sites/TeamName. Click on the site name to open its details.
3. Check the storage used value
   In the site details panel, look for the Storage used field. This number represents the total storage consumed by the entire site collection, including all hidden folders and system libraries. Write down this number.
4. Compare with the Teams admin center report
   Open the Teams admin center at admin.teams.microsoft.com. Go to Teams > Manage teams. Find your team and click on it. In the team details, look for the Storage section. The number shown here should match the SharePoint admin center’s “Storage used” value, because both count the entire site collection.
5. Use PowerShell for the exact number
   If you want a precise number in megabytes, open SharePoint Online Management Shell and run the following command: Get-SPOSite -Identity "https://yourtenant.sharepoint.com/sites/TeamName" | Select StorageUsageCurrent. The output is the storage used in megabytes. This is the same number that the Teams admin center uses.

Understanding the Difference in the Document Library

If you navigate to the site’s document library in SharePoint and look at the storage metrics, you will see a smaller number. This is because the library view only shows files in the “Documents” library, not the hidden folders. To see the full site collection usage, use the “Storage Metrics” page in site settings, which lists all libraries and their sizes.

If Teams Storage Report Still Does Not Match SharePoint

Teams Shows More Storage Than SharePoint Admin Center

If the Teams admin center shows a higher number than the SharePoint admin center, it is likely because the Teams report includes temporary files or system metadata that SharePoint does not include in its “Storage used” field. Refresh the page in both admin centers after a few minutes, because the reports may update at different intervals. If the difference is more than 1 GB, check the site collection for orphaned files or version history. Use the Get-SPOSite cmdlet to see the exact usage and compare it with the Teams report.

Teams Shows Less Storage Than SharePoint

This situation is rare but can happen if the Teams admin center report is cached. Sign out of the Teams admin center and sign back in. Then refresh the team’s storage section. If the issue persists, wait up to 24 hours for the data to synchronize. The SharePoint admin center is the authoritative source, so trust that number for capacity planning.

New Team Has Zero Storage in Teams Admin Center

A newly created team may show 0 MB in the Teams admin center until the site collection is fully provisioned. This is normal and can take up to 30 minutes. After that, the storage report will show the actual usage. If it remains at zero after an hour, run Get-SPOSite -Identity "SiteURL" to verify the site exists and has a quota assigned.

Teams Admin Center vs SharePoint Admin Center: Storage Reporting Differences

Item	Teams Admin Center	SharePoint Admin Center
Data Source	Site collection usage from SharePoint	Site collection usage from SharePoint
Includes Hidden Folders	Yes, includes Teams data folder	Yes, in “Storage used” field
Update Frequency	Near real-time	Near real-time
Default View	Team-level summary	Site-level summary
Best for Capacity Planning	Quick overview	Authoritative number

Both admin centers pull from the same underlying storage data, so the numbers should match after a refresh. If you see a mismatch, always verify with the SharePoint admin center or PowerShell.

Now you know why the Teams storage report can differ from SharePoint for a new team and how to verify the actual usage. Use the SharePoint admin center’s “Storage used” value as your reference point. To get the most accurate number, run the Get-SPOSite cmdlet in SharePoint Online Management Shell. For ongoing monitoring, set up a scheduled script that logs storage usage weekly. This helps you track growth and avoid surprises when your team approaches the storage limit.
