The user is encountering a 404 File Not Found error when trying to access a SharePoint site connected to Microsoft Teams.

How to Fix Microsoft Teams SharePoint Site 404 Error

Product: Microsoft SharePoint
Device & OS: not provided
Scenario: Accessing a Teams-connected SharePoint site after a folder or document was created.
Observed behavior: The SharePoint site becomes completely inaccessible, displaying a '404 File Not Found' error across multiple web browsers and in private browsing mode.

Before you start

Verify that you have the correct and most up-to-date URL for the SharePoint site, and check if you have SharePoint administrator privileges, as they are required to review active sites and restore deleted ones.

Solution 1Recommended

Check and Restore Deleted SharePoint Sites in Admin Center

Use this method if the site was accidentally deleted, which is the most common cause of a sudden 404 error on a Teams-connected SharePoint site.

When a Team or its connected SharePoint site is deleted by another user, the site becomes immediately inaccessible, returning a 404 error. Administrators can easily recover these sites from the recycle bin.

Access SharePoint Admin Center

Check Active Sites

Under the 'Sites' menu on the left panel, click on 'Active sites' to see if the site is still listed or if its URL was changed.

Locate Deleted Sites

If the site is missing from the active list, click on 'Deleted sites' under the same 'Sites' dropdown menu.

Restore the Site

Select the missing Team site from the list and click the 'Restore' button on the toolbar to recover the site collection.

Check and Restore Deleted SharePoint Sites in Admin Center

Admin Access Required: You must be a SharePoint Administrator or Global Administrator to access the admin center and restore deleted sites.

Solution 2

Verify Direct Site Access via Office.com

Sometimes the access tab in Microsoft Teams is broken or misconfigured, but the SharePoint site itself is still active.

Solution 3

Submit a Microsoft 365 Support Request

If the site is neither active nor in the deleted sites list, a backend routing issue or permanent deletion may have occurred.

Frequently Asked Questions

Why did my Microsoft Teams SharePoint site suddenly disappear?

A sudden disappearance resulting in a 404 error usually occurs if the underlying SharePoint site collection was accidentally deleted by an administrator, the site's URL was recently changed, or there is a backend synchronization delay between Teams and SharePoint.

How long are deleted SharePoint sites kept in the recycle bin?

Deleted SharePoint site collections are retained in the SharePoint admin center's 'Deleted sites' section for 93 days. After this 93-day retention period, they are permanently deleted and cannot be restored.

Can a standard user restore a deleted SharePoint site?

No, standard team members or owners cannot restore a deleted site collection themselves. You must contact a user with SharePoint Administrator or Global Administrator privileges to restore the site from the Microsoft 365 admin center.

Does changing a SharePoint site name alter its URL?

Changing the site's display name does not automatically change the site's URL. However, if an administrator specifically modifies the site address (URL) via the admin center, old links in Teams will break and return a 404 error until they are updated to the new address.
