Question details

Developers want to know how to open or navigate to OneDrive directly from an Outlook Desktop add-in using the Office.js API.

How to Open OneDrive from an Outlook Desktop Add-in Using Office.js

Product: Outlook Add-in (Office.js)
Device & OS: not provided
Scenario: Creating an Outlook desktop add-in and attempting to switch the navigation interface to OneDrive or open OneDrive modules.
Observed behavior: Office.js does not provide an API for switching Outlook desktop modules or opening OneDrive directly inside the Outlook navigation rail.

Before you start

Ensure you have the latest version of the Office JavaScript API (Office.js) and active credentials if you plan to use the Microsoft Graph API as a workaround.

Solution 1Recommended

Use displayDialogAsync to Open OneDrive in a Dialog or Browser

Since direct navigation within the Outlook client is unsupported, use the Dialog API to open the OneDrive web interface in a separate window.

The Office JavaScript API restricts add-ins from changing the main Outlook desktop navigation modules. However, you can utilize the Dialog API to securely authenticate and display external web content, such as OneDrive.

Initialize the Dialog API

In your add-in's JavaScript code, prepare the URL for the OneDrive web interface or your custom OneDrive file picker.

Call displayDialogAsync

Execute Office.context.ui.displayDialogAsync('https://onedrive.live.com', {height: 50, width: 50}, function (asyncResult) { ... }); to trigger the popup.

Handle Dialog Events

Set up a callback function to handle messages or events from the dialog box, allowing your add-in to know when the user has finished interacting with OneDrive.

Use displayDialogAsync to Open OneDrive in a Dialog or Browser

Navigation Limitation: This method opens OneDrive in a dialog box or default browser, not directly within the Outlook desktop module rail.

Solution 2

Access OneDrive Files Programmatically via Microsoft Graph

If you need to interact with OneDrive files rather than showing the UI, use the Microsoft Graph API.

Solution 3

Submit a Feature Request to the Office.js Team

Report the API limitation to Microsoft to advocate for future support of module switching.

Frequently Asked Questions

Can I switch Outlook desktop modules directly using Office.js?

No, currently the Office JavaScript API (Office.js) does not provide any methods to switch between Outlook desktop modules (like moving from Mail to Calendar or OneDrive) directly within the navigation interface.

Does displayDialogAsync open OneDrive inside the Outlook window?

The displayDialogAsync method opens a separate dialog box or launches the user's default web browser. It does not embed the OneDrive interface natively within the main Outlook client window.

Where can I request new API features for Outlook add-ins?

You can submit feature requests, report bugs, or discuss API limitations directly with the development team on the official GitHub repository at github.com/OfficeDev/office-js/issues.
