How to Fix Power Automate SharePoint Create File Locked Error

Product: Power Automate / SharePoint Online
Device & OS: not provided
Scenario: Running a custom Power Automate flow to automatically create or update a file within a SharePoint document library.
Observed behavior: The flow execution fails and returns an error indicating the target file is locked for shared use, preventing the creation or modification action.

Before you start

Verify that you have sufficient permissions to create and edit files in the target SharePoint document library, and ensure no other users currently have the target file open.

Solution 1Recommended

Test Direct File Creation in SharePoint

Determine if the issue is with the SharePoint library's configuration or isolated to the Power Automate flow itself.

Before modifying the flow, it is crucial to test whether the SharePoint library allows manual file creation by the flow owner. This isolates permission or site-level issues from flow-specific logic.

Navigate to the SharePoint Library

Open your web browser, log in to Microsoft 365, and navigate to the specific SharePoint Online document library where the flow is trying to create the file.

Create a New File Manually

Click on the 'New' button in the SharePoint ribbon and select 'Word document' or 'Excel workbook' to try creating a blank file directly.

Evaluate the Result

If you can create the file successfully without errors, the library permissions are correct, meaning the locked error is caused by your specific Power Automate flow configuration.

Solution 2

Review and Adjust Power Automate Flow Settings

Check the flow for conflicting actions, incorrect paths, or looping mechanisms that might cause the file to lock itself.

Frequently Asked Questions

Why does Power Automate say my SharePoint file is locked?

This error usually occurs when the flow attempts to modify or overwrite a file that is currently open by a user, being synced by OneDrive, or being accessed simultaneously by another parallel action within your flow.

How long does a SharePoint file lock last?

If a file is locked by a process or user session that disconnected unexpectedly, the lock typically expires automatically after 10 to 15 minutes of inactivity.

Can I force unlock a file in SharePoint?

Yes. If you have site owner or admin privileges, you can often release a lock by requiring check-out in the library settings, checking the file out yourself, and then checking it back in. Alternatively, Microsoft 365 admins can end user sessions.

Do loop actions in Power Automate cause file locking?

Yes. If an 'Apply to each' loop has concurrency control enabled and multiple iterations attempt to update the exact same file at the same time, SharePoint will lock the file. To fix this, disable concurrency or set the degree of parallelism to 1.
