Solving the OneDrive File Renaming Puzzle on Windows Server 2019

Is Bug in FSLogix Stopping From Renaming OneDrive Files? Why Can’t You Rename Folders in OneDrive on Windows Server 2019?

If you are a system administrator, you know the feeling. A strange problem appears that makes no sense. It disrupts work for your users, and the usual fixes do not work. Recently, a tricky bug has affected many teams using Windows Server 2019. It involves OneDrive and a tool called FSLogix. This issue stops people from doing something very simple: renaming their files and folders.

This article will walk you through this problem in simple terms. We will look at what causes it, who it affects, and most importantly, how to fix it for good. You can think of this as a guide to help you solve this specific headache and get your team working smoothly again.

What Does This OneDrive Bug Look Like?

Imagine you or one of your users is working in OneDrive. You create a folder for a new project. The system names it “New Folder.” Naturally, you try to rename it to something useful, like “Project Alpha Reports.” But it doesn’t work. Instead of changing the name, a vague error message pops up with no helpful information.

This is the core of the problem. It happens with both files and folders. The default name cannot be changed. This isn’t just a minor glitch; it is a major roadblock. How can teams organize their work if they cannot name their own files? It makes OneDrive nearly impossible to use for daily tasks. Even trying to rename files using technical tools like PowerShell or the Command Prompt fails. The result is a messy OneDrive folder filled with items named “New Document” and “New Folder,” leading to confusion and lost productivity.

Pinpointing the Cause: A Specific Environment

This error does not happen to everyone. It only appears when a specific combination of software is used. Understanding this is key to confirming if this is the problem you are facing.

The bug shows up in this environment:

• The Server: The computer system is running Windows Server 2019.
• The Tool: You are using FSLogix to manage user profiles.
• The Application: The problem occurs inside OneDrive.

What is FSLogix?

Let’s quickly talk about FSLogix. Microsoft bought this company in 2018. It is a tool used in virtual desktop environments, like those with many users connecting to a central server. Its main job is to manage user profiles. A user profile is what holds all of a person’s settings and data, like their desktop background, saved passwords, and documents. FSLogix puts this profile into a container that can be quickly attached or detached as a user logs in or out. This makes logging in much faster and more reliable.

The FSLogix Connection

Administrators noticed a clear pattern. The renaming problem only happened to users whose profiles were managed by FSLogix. In many companies, administrators are not part of the FSLogix system to make troubleshooting easier. Their profiles are stored locally on the server’s main drive (the C:\ drive). For these local users, OneDrive worked perfectly. They could rename files and folders without any issues.

This discovery was the “aha!” moment. The problem was not with Windows Server 2019 alone, and it was not a general OneDrive bug. It was a conflict between OneDrive and specific versions of FSLogix. Tests were done using different FSLogix versions, including 25.02 and 25.06, and the bug was present in all of them. It was clearly connected to how FSLogix handled the user’s OneDrive data.

The Frustrating Search for a Fix

Finding the cause is one thing; finding a solution is another. The administrators who first discovered this bug did what you would do: they asked Microsoft for help. They opened a support ticket on July 14, 2025. They explained the problem in detail and waited for a solution from the experts.

However, the journey was not easy. After weeks of back-and-forth communication, the support ticket was closed on September 1, 2025. The final message was that the problem was “outside the scope of support.” The support team was unable to provide a fix. This was a dead end. The people facing the issue had done everything right, but even the official support channel could not help them. Their only remaining hope was to share the problem with the wider community of IT professionals, hoping someone else had found an answer.

The Solution: A Simple Update

And the community delivered. The frustrating bug that stumped even Microsoft support has a clear and confirmed solution. The problem has been fixed in a newer version of FSLogix.

The solution is to update your FSLogix installation to version 2509 (released September 10, 2025) or any newer version.

Here is a straightforward plan to resolve the issue:

1. Confirm Your Version. First, check which version of FSLogix is running on your servers. You can usually find this in the “Apps & features” or “Programs and Features” section of the Windows settings or Control Panel. If you see a version older than 2509, you are likely affected by this bug.
2. Download the Update. Go to the official Microsoft website where FSLogix is available for download. Always get software from official sources to ensure it is safe and secure. Download the latest available version.
3. Install the New Version. Plan a maintenance window to install the update on your Windows Server 2019 machines. As with any system update, it is best to do this during off-hours to avoid disrupting your users. Once the update is complete, the conflict with OneDrive will be resolved.

Users who have installed the updated version of FSLogix have confirmed that the ability to rename files and folders in OneDrive is immediately restored. The error disappears, and everything works as it should.

This situation is a powerful reminder that in the world of IT, sometimes the best support comes from the community. It also shows why keeping all parts of your system, including tools like FSLogix, fully updated is not just a best practice—it is essential for preventing problems that can stop work in its tracks.
