If your organization has access to a commercial Microsoft 365 subscription, you can edit files in the web portal using your Microsoft 365 apps. During the editing session, files are automatically saved, and all versions are tracked.
Your administrator must turn on this feature before it can be used.
Advanced functionality includes:
- Quickly view or edit files directly from the web portal, without needing to download files or use local applications.
- Access a wide range of formatting tools to manage fonts, images, charts, styles, and more.
- Edit and collaborate using the Track Changes and Commenting features.
- Track file changes and revisions automatically through the auto-save feature.
- Collaborate with co-authors in real time.
Supported File Formats
The following file formats can be edited using Microsoft 365 apps:
- Microsoft Word (.docx)
- Microsoft PowerPoint (.pptx)
- Microsoft Excel (.xlsx)
Notifications and File Locking
- In the Web Portal, a file that is being actively edited within a Microsoft 365 app will be marked with a Web Edit icon. Team Share subscribers will still be able to launch this file from the web portal.
- In the desktop client, a file that is being actively edited will be automatically protected by the File and Folder Locking feature and marked with a lock icon. Team Share subscribers will not be able to edit this file using applications on their local machines.
Launching a Microsoft 365 App
To view or edit files using Microsoft 365 apps:
- In the Files tab of the web portal, navigate to the file that you want to view.
- Right-click a supported file, point to Open in, and select the appropriate Microsoft 365 app (in this instance, we are selecting Word Online).The file automatically locks and will be marked with an Editing icon in the web portal.
- If you are not logged in to Microsoft 365, you will be prompted to sign in. Click the Sign in with a work or school account button to continue.After you are authenticated, the file opens in the Microsoft 365 app. Depending on administrative settings, you might only have the option to view files. Contact your administrator for more information.
- When working in your Microsoft 365 apps, you can access advanced functionality, including:
