Can Microsoft 365 PWA Open Local Files Offline?
Question details
The user wants to know if Microsoft 365 Progressive Web Apps (PWAs) installed via Microsoft Edge can be used to open and edit local Excel or Word documents offline.
- Product
- Microsoft 365 PWA
- Device & OS
- not provided
- Scenario
- Attempting to open a local document directly from the computer's hard drive for offline editing using the Microsoft 365 PWA.
- Observed behavior
- The PWA fails to open the local file for offline editing; instead, it downloads the file, redirects to the web version, or requires an installed desktop application.
Verify whether you have a desktop Office suite installed on your computer, as web apps natively require internet access and cloud storage for document editing.
Use an Installed Desktop Application for Local Files
Since PWAs are designed for cloud-based files, you must use a traditional desktop application to edit local files offline.
Microsoft 365 Progressive Web Apps cannot normally be configured to open local Word or Excel files offline by default. If you attempt to open a local file, the system relies on locally installed software.
Open your computer's File Explorer and navigate to the folder where your local Word or Excel file is saved.
Right-click the file, hover over 'Open with', and select your installed desktop Office application (such as Excel or Word) from the context menu.
Upload the File to OneDrive to Use the PWA
If you want to edit the file using the Microsoft 365 PWA, you must first upload the local file to Microsoft's cloud storage while connected to the internet.
Edit Local Files Offline Seamlessly with WPS Office
Because Microsoft 365 PWAs require an internet connection and cloud storage to edit files, they are not suitable for true offline local editing. WPS Office provides a lightweight, fully functional desktop alternative that lets you open, edit, and save local documents offline without forcing cloud uploads.
- 1. Download and Install: Download the free WPS Office desktop suite from the official website and install it on your computer.
- 2. Set as Default: During installation, or by right-clicking a file, set WPS Office as the default application for Office formats.
- 3. Edit Offline: Double-click any local Word, Excel, or PowerPoint file to instantly open and edit it offline.
Frequently Asked Questions
Why does my local file download instead of opening in the Microsoft 365 PWA?
Progressive Web Apps are browser-based and optimized for cloud storage (OneDrive/SharePoint). When you try to open a local file in the PWA environment without a desktop app installed, the browser defaults to treating the file as a standard web download.
Can I force Microsoft Edge to open local Excel files in the PWA?
No, Microsoft Edge and the M365 PWA cannot be configured to edit local files offline by default. To edit a file in the PWA, it must first be uploaded to your Microsoft cloud storage.
Does the Microsoft 365 PWA work offline at all?
The Microsoft 365 PWA has very limited offline capabilities. While it may allow you to view certain recently accessed cloud documents if offline caching is enabled, it does not support browsing and editing local files directly from your computer's hard drive while offline.
