How to Open Office Web Documents in the Same Tab as Outlook
Question details
The user wants to open Word, Excel, and PowerPoint files within the same application tab instead of launching a new browser tab or OneDrive when using the Outlook web PWA.

- Product
- Outlook Web PWA
- Device & OS
- not provided
- Scenario
- Viewing and managing Office document attachments or links while operating within the Outlook web Progressive Web App (PWA).
- Observed behavior
- Office documents launch in OneDrive and open in a separate browser tab instead of staying within the Outlook PWA tab.
Before troubleshooting, note that the Outlook Web PWA handles external document links differently than native desktop applications. Ensure your browser is set to allow pop-ups and new tabs from Outlook to view your documents successfully.
Understand Web Document Tab Behavior in Outlook PWA
Currently, Microsoft Office web apps do not have equivalent PWA versions, meaning files will inherently open in a new tab via OneDrive.
When you use the Outlook web PWA, it acts as a standalone application. However, Word, Excel, and PowerPoint on the web do not have their own standalone PWA integrations that can render within the same Outlook window.
Consequently, clicking an Office document link or attachment forces the file to open through OneDrive in a standard browser tab. If you wish to see this behavior changed in future updates, submitting feedback to Microsoft is the official course of action.
To avoid opening a new tab, single-click the document attachment in your Outlook email. This will utilize the built-in previewer in the reading pane rather than launching the full web app.
If you double-click or select 'Open in browser', acknowledge that the document will securely open in a new browser tab via OneDrive.
To request a change to this behavior, click 'Help' and then 'Feedback' within your Outlook web interface to submit a feature request to the developers.

Frequently Asked Questions
Why do my Excel attachments open in OneDrive instead of Outlook?
Excel and other Office web apps lack a Progressive Web App (PWA) version compatible with the Outlook PWA. Therefore, the Outlook PWA hands the file over to OneDrive, which opens it in a new web browser tab.
Can I force Outlook Web to preview documents without opening a new tab?
Yes, you can use the built-in preview feature in Outlook on the web. Single-click the attachment to preview it directly within the reading pane instead of double-clicking or selecting 'Open', which launches the file in a new tab.
Will Microsoft add PWA support for Word and Excel?
Microsoft has not officially announced standalone PWA integration for Word, Excel, or PowerPoint that would allow them to open within the Outlook PWA tab. Users are encouraged to submit feature requests via the Microsoft Feedback portal.
Is there a way to view all my Office files in one window?
While Microsoft Office web apps open in separate browser tabs, you can use desktop applications like WPS Office that feature a unified, multi-tabbed interface for all your document types in a single window.
