How to Open OneDrive Files in Desktop Apps From the Browser

Opening a OneDrive file from your browser usually launches the web version of the app. You want the file to open directly in the installed desktop application like Word, Excel, or PowerPoint. This behavior is controlled by a browser setting and a OneDrive file handler. This article explains how to force desktop apps to open when you click a file link in the browser.

The browser often opens Office files in the web app by default because the web app loads faster. However, you can change this default to always open files in the desktop application. The change is made in the browser settings and applies to all files in OneDrive, SharePoint, and Teams.

This guide covers the steps for Chrome, Edge, and Firefox. It also explains what to do if the setting does not stick or if the desktop app still does not open.

Why Files Open in the Browser Instead of the Desktop App

When you click a link to a Word document on OneDrive, your browser checks the file type. If the browser has a built-in viewer or a web app handler for that file type, it opens the file in the browser. Office Online is the default web handler for .docx, .xlsx, .pptx, and .pdf files. The browser prefers the web app because it starts faster and does not require a local installation.

The desktop app does not open unless you manually change the browser’s file handling behavior. Each browser stores this setting in a different location. Once changed, the browser passes the file URL to the installed Office application, which launches and downloads the file from OneDrive.

Steps to Change Browser Settings for Desktop App Launch

The steps differ for each browser. Use the section that matches your default browser.

Google Chrome

1. Open Chrome Settings
   In the address bar, type chrome://settings/content/pdfDocuments and press Enter. This opens the PDF document settings.
2. Turn off PDF viewer
   Toggle the switch next to “Download PDF files instead of automatically opening them in Chrome” to the ON position. This forces Chrome to download the file instead of previewing it. The desktop app will then open the downloaded file.
3. Change Office file handling
   Type chrome://settings/handlers in the address bar. Under “Protocol handlers,” look for “mailto” or other handlers. Chrome does not allow you to set a default handler for Office file types directly. Instead, when you click a file link, right-click the link and select “Save link as” or use the download option. Then open the file from the download bar. For a direct open experience, use Edge or Firefox.

Microsoft Edge

1. Open Edge Settings
   Click the three-dot menu in the top-right corner and select “Settings.” In the left sidebar, click “Cookies and site permissions.”
2. Find PDF documents
   Scroll down and click “PDF documents.” Toggle the switch for “Always download PDF files” to ON. This prevents Edge from opening PDFs in its built-in viewer.
3. Set Office file protocol
   Edge uses the Microsoft 365 protocol handler. In the address bar, type edge://settings/defaultBrowser. Under “Protocol handlers,” click “Manage protocol handlers.” Ensure that “Microsoft Office” is listed and set as the default handler for the ms-word:, ms-powerpoint:, and ms-excel: protocols. If not, click the three-dot menu next to each and select “Set as default.”
4. Test the change
   Go to your OneDrive in Edge and click a Word file. It should now open in the desktop Word app.

Mozilla Firefox

1. Open Firefox Options
   Click the hamburger menu in the top-right corner and select “Settings.” In the left sidebar, click “General.”
2. Scroll to Applications
   Scroll down to the “Applications” section. This lists all file types and their current handling actions.
3. Change Office file types
   In the search box, type docx. Find the entry for “Microsoft Word Document” or “Office Open XML Document.” Click the action dropdown next to it. Select “Use other app” and browse to the location of your Office application. Repeat for xlsx and pptx.
4. Set PDF handling
   Search for pdf. Change the action from “Preview in Firefox” to “Use other app” and select your PDF reader or Office app if you want it to open in Word.

If the Desktop App Still Does Not Open

Sometimes the browser setting alone is not enough. The following issues can prevent the desktop app from launching.

OneDrive File Link Opens the Web App Instead of the Desktop App

This happens when the browser does not recognize the file protocol handler. In Edge, go to edge://settings/defaultBrowser and click “Manage protocol handlers.” Verify that the ms-word: protocol is set to open in Microsoft Word. If it is missing, install or repair Microsoft 365 apps from the Microsoft 365 admin center or run the Office repair tool from Control Panel > Programs > Microsoft 365 > Change > Quick Repair.

Desktop App Asks to Sign In Every Time

The desktop app must be signed in with the same account used in the browser. Open Word, go to File > Account, and check the user name. If it is different, sign out and sign in with the correct work or school account. If the account is correct, clear the browser cache and cookies for the OneDrive domain and try again.

Browser Resets the File Handling Setting After Update

Browser updates sometimes reset file handling preferences. After a major update, check the settings again. In Firefox, the Applications list is preserved across updates. In Chrome and Edge, the PDF download toggle may reset. Reapply the setting after each browser update.

Browser Settings for Desktop vs Web App: Comparison

Item	Open in Web App	Open in Desktop App
Default behavior	File opens in Office Online in the browser tab	File opens in installed Word, Excel, or PowerPoint
Browser setting required	None (default)	Change PDF handling and protocol handlers
File location after open	File stays on OneDrive server	File is downloaded to a temp folder and saved back to OneDrive
Offline access	Requires internet connection	Works offline if file is synced locally
Collaboration features	Real-time co-authoring in browser	Co-authoring available if file is synced via OneDrive

You can now open OneDrive files directly in desktop applications from your browser by adjusting the file handling settings in Chrome, Edge, or Firefox. Test the change by clicking a Word or Excel file in your OneDrive library. If the desktop app does not launch, verify that the protocol handlers are set correctly and that your Office apps are signed in with the same account. For the most reliable experience, use Microsoft Edge with the protocol handlers set to Microsoft Office.
