Teams Channel Files Tab Shows Blank Page Until “Reload Pane” Is Manually Triggered

Hello Christian Berg Smith,

I am sorry to hear that you’re experiencing an issue where the Shared/Files tab in Microsoft Teams is not loading files correctly.

To better understand the issue, could you please clarify the following:

• Does the issue also occur in Teams on the web?
• Does this happen in all channels or only specific channels?

In the meantime, please try the following troubleshooting steps:

1. Review the following Microsoft article and check whether any of the scenarios described match your issue: https://learn.microsoft.com/en-us/troubleshoot/microsoftteams/files/access-files-tab-errors?wt.mc_i…

If any of the scenarios match, please try the suggested steps and let me know whether they help resolve the issue.

1. Update Microsoft Teams to the latest version.
2. Sign out of Teams and sign back in. This refreshes the account session and may help resolve the issue.
3. Clear the Teams cache. Cached data can sometimes cause loading problems. Please refer to: https://learn.microsoft.com/en-us/troubleshoot/microsoftteams/teams-administration/clear-teams-cache
4. If the issue persists, please uninstall and reinstall the Teams application.

Additionally, I found a user discussion describing a similar issue with the Shared tab that you may refer to: https://blog-en.topedia.com/2026/02/shared-tab-in-teams-channels-is-empty-after-the-files-tab-trans…

Users are currently testing on newest version 26072.521.4595.7966 to see if issue is fixed.

Based on the available information, this behavior aligns with a generic Files tab loading issue in Teams rather than a specific documented error state.

Use the following checks and mitigations that apply to Files tabs in Teams channels:

1. Verify SharePoint availability and permissions
   • The Files tab in a standard channel surfaces content from the underlying SharePoint document library.
   • Confirm that affected users can open the corresponding SharePoint site and document library directly in a browser and see the files.
   • If users cannot access the SharePoint site or library, review and correct their SharePoint permissions.
2. Check for orphaned or misconfigured Microsoft 365 group ownership
   • For standard channels, issues with the associated Microsoft 365 group can affect file access.
   • If the group has become orphaned (for example, the only owner left the organization), assign a new owner to the Microsoft 365 group associated with the team. This is done by a Microsoft 365 admin. For details, see “Assign a new owner to an orphaned group.”
3. Validate that the SharePoint site collection link is intact
   • For both standard and private channels, confirm that the SharePoint site or site collection backing the channel is still present and correctly linked.
   • If the site collection link is broken or the site has been moved/deleted, restore or relink it so Teams can load the files.
4. Check for Conditional Access or related policies
   • If Conditional Access policies are applied to SharePoint or OneDrive, they can interfere with embedded content loading in Teams tabs.
   • Validate that affected users meet Conditional Access requirements (device compliance, network location, browser/app conditions) and that policies are not blocking SharePoint when accessed via Teams.
5. Run tenant-level diagnostics (admin)
   • A Microsoft 365 admin can run the self-diagnostics for Teams file access issues in the Microsoft 365 admin center. This tool checks for known configuration and service issues that can affect Files tabs.
6. Use alternative access paths while investigating
   • If the Files tab intermittently shows blank content, users can:
     • Open the underlying SharePoint document library directly in a browser.
     • Use OneDrive sync or the SharePoint site to access the same files.

If the issue persists after confirming SharePoint access, group ownership, and Conditional Access, collect client logs and open a support case so Microsoft can investigate client-specific or service-side regressions related to the current Teams build.
