Office-Addin-TaskPane-SSO

This repository contains the source code used by the Yo Office generator when you create a new Office Add-in that appears in the task pane. You can also use this repository as a sample to base your own project from if you choose not to use the generator.

TypeScript

This template is written using TypeScript. For the JavaScript version of this template, go to Office-Addin-TaskPane-SSO-JS.

Instructions

Run the following command to configure single-sign on for your add-in project.

    $ npm run configure-sso

A web browser window will open and prompt you to sign in to Azure. Sign in to Azure using your Microsoft 365 administrator credentials. These credentials will be used to register a new application in Azure and configure the settings required by SSO.
Run the following command to build the project, start the local web server, and sideload your add-in in the previously selected Office client application.

    $ npm start

> [!NOTE]
> Office Add-ins should use HTTPS, not HTTP, even when you are developing. If you are prompted to install a certificate after you run the following command, accept the prompt to install the certificate that the Yeoman generator provide.

In the Office client application that opens when you run the previous command (i.e., Excel, Word or PowerPoint), make sure that you're signed in with a user that's a member of the same Microsoft 365 organization as the Microsoft 365 administrator account that you used to connect to Azure while configuring SSO in step 3 of the previous section. Doing so establishes the appropriate conditions for SSO to succeed.
In the Office client application, choose the Home tab, and then choose the Show Task Pane button in the ribbon to open the add-in task pane. The following image shows this button in Excel.
At the bottom of the task pane, choose the Get My User Profile Information button to initiate the SSO process.

If a dialog window appears to request permissions on behalf of the add-in, this means that SSO is not supported for your scenario and the add-in has instead fallen back to an alternate method of user authentication. This may occur when the tenant administrator hasn't granted consent for the add-in to access Microsoft Graph, or when the user isn't signed into Office with a valid Microsoft account or Microsoft 365 Education or Work account. Choose the Accept button in the dialog window to continue.
The add-in retrieves profile information for the signed-in user and writes it to the document.
