Question details

The user is attempting to change a PowerPoint file's access from edit to view-only but encounters an error stating they are not the owner, preventing the permission change.

Product: PowerPoint, SharePoint, OneDrive
Device & OS: not provided
Scenario: Using the Manage Access dialog to restrict existing user permissions on a shared presentation from Edit to View-Only.
Observed behavior: The system throws a 'not the owner' error, which actually refers to lacking SharePoint site or Teams channel ownership rights, rather than the file's 'Created By' attribute.

Before you start

Examine the presentation's URL in your web browser to verify whether the file is stored in your personal OneDrive or a shared organization SharePoint site, as this dictates who has the authority to change permissions.

Solution 1Recommended

Request Permission Changes from the Site Administrator

The most effective way to resolve ownership conflicts when you do not hold administrative rights to the SharePoint site or Teams channel.

In shared Microsoft 365 environments, file management permissions are governed by the overarching site or channel ownership rules. Even if you created the specific PowerPoint file, you may lack the necessary Full Control rights at the directory level to alter access settings.

Identify the storage location

Check the address bar of the open presentation. A URL containing your organization's domain followed by '/sites/' indicates a SharePoint site.

Contact the administrator

Reach out to the designated SharePoint site owner or your organization's Microsoft 365 IT support team.

Request an access update

Ask the administrator to either downgrade the specific users' permissions to 'View-Only' for that file, or request that they grant you 'Site Owner' status so you can manage the Manage Access dialog yourself.

Solution 2

Reconfigure Site-Level User Permissions

Use this solution if you already possess or have recently been granted administrative privileges for the SharePoint site.

Frequently Asked Questions

Why do I get a 'not the owner' error when I am the one who created the PowerPoint file?

In enterprise environments like SharePoint or Microsoft Teams, permission management is dictated by the site or channel's overarching ownership rules, not the individual file's 'Created By' attribute. You must have site owner rights to alter user access levels.

How can I tell if my presentation is hosted on personal OneDrive or a shared SharePoint site?

Open the presentation in your web browser and inspect the URL. If the URL contains 'my.sharepoint.com', it is typically stored in your personal OneDrive. If it contains your organization's domain followed by '/sites/', it is hosted on a shared SharePoint site.

Will removing a user's edit access on a SharePoint site affect their other files?

Yes. If an administrator changes or removes a user's permissions at the broader site or folder level rather than applying a strict file-level exception, it will affect that user's ability to access or edit all other documents stored in that location.
