Report the Issue to Microsoft Q&A

Because this involves an on-premises SharePoint Server 2019 bug, consulting the dedicated Microsoft Q&A forum is the recommended path for a definitive fix.

This upload failure is often related to specific patch levels or server configurations in SharePoint 2019 on-premises environments. Microsoft engineers and community experts on the official forum can provide patch-specific guidance.

Gather your environment details

Note down the exact error behavior, the web browser you are using, and the upload method (e.g., drag-and-drop or using the Upload button).

Identify your patch level

Contact your IT administrator to confirm the current cumulative update or patch level installed on your SharePoint Server 2019 environment.

Post on the Microsoft Q&A forum

Navigate to the Microsoft Q&A SharePoint Server forum (https://learn.microsoft.com/en-us/answers/tags/41/office-sp-server). Submit your question, ensuring you include the details gathered in the previous steps and the 'SharePoint Server' tag.

Solution 2

Verify Versioning and Check-Out Requirements

Confirming your library's versioning and check-out settings can rule out configuration-based blocks when replacing files.

Frequently Asked Questions

Why does my SharePoint 2019 upload fail with a red X?

A red X during upload usually indicates a server-side processing error, a locked file, or a browser compatibility issue. In SharePoint Server 2019 on-premises, this can sometimes be tied to specific server patch levels.

Does SharePoint automatically create a new version when uploading a file with the same name?

Yes, as long as versioning is enabled in the document library settings and the file is not currently checked out or locked for editing by another user.

How can I bypass a locked toolbar in a SharePoint document library?

If your library toolbar becomes temporarily locked after a failed upload, clearing your browser cache, hard-refreshing the page (Ctrl + F5), or attempting the action in a different browser can often restore functionality.
