Virtual appointments

This tutorial describes concepts for virtual appointment applications. After completing this tutorial and the associated Sample Builder, you'll understand common use cases that a virtual appointments application delivers, the Microsoft technologies that can help you build those uses cases, and have built a sample application integrating Microsoft 365 and Azure that you can use to demo and explore further.

Virtual appointments are a communication pattern where a consumer and a business assemble for a scheduled appointment. The organizational boundary between consumer and business, and scheduled nature of the interaction, are key attributes of most virtual appointments. Many industries operate virtual appointments: meetings with a healthcare provider, a loan officer, or a product support technician.

No matter the industry, there are at least three personas involved in a virtual appointment and certain tasks they accomplish:

• Office Manager. The office manager configures the business’ availability and booking rules for providers and consumers.
• Provider. The provider gets on the call with the consumer. They must be able to view upcoming virtual appointments and join the virtual appointment and engage in communication.
• Consumer. The consumer who schedules and motivates the appointment. They must schedule an appointment, enjoy reminders of the appointment, typically through SMS or email, and join the virtual appointment and engage in communication.

Azure and Teams are interoperable. This interoperability gives organizations choice in how they deliver virtual appointments using Microsoft's cloud. Three examples include:

• Microsoft 365 provides a zero-code suite for virtual appointments using Microsoft Teams and Bookings. This is the easiest option but customization is limited. Check out this video for an introduction.
• Microsoft 365 + Azure hybrid. Combine Microsoft 365 Teams and Bookings with a custom Azure application for the consumer experience. Organizations take advantage of Microsoft 365's employee familiarity but customize and embed the consumer appointment experience in their own application.
• Azure custom. Build the entire solution on Azure primitives: the business experience, the consumer experience, and scheduling systems.

These three implementation options are columns in the table below, while each row provides a use case and the enabling technologies.

Persona	Use Case	Microsoft 365	Microsoft 365 + Azure hybrid	Azure Custom
Manager	Configure Business Availability	Bookings	Bookings	Custom
Provider	Managing upcoming appointments	Outlook & Teams	Outlook & Teams	Custom
Provider	Join the appointment	Teams	Teams	Azure Communication Services Calling & Chat
Consumer	Schedule an appointment	Bookings	Bookings	Azure Communication Services Rooms
Consumer	Be reminded of an appointment	Bookings	Bookings	Azure Communication Services SMS
Consumer	Join the appointment	Teams or virtual appointments	Azure Communication Services Calling & Chat	Azure Communication Services Calling & Chat

There are other ways to customize and combine Microsoft tools to deliver a virtual appointments experience:

• Replace Bookings with a custom scheduling experience with Graph. You can build your own consumer-facing scheduling experience that controls Microsoft 365 meetings with Graph APIs.
• Replace Teams’ provider experience with Azure. You can still use Microsoft 365 and Bookings to manage meetings but have the business user launch a custom Azure application to join the Teams meeting. This might be useful where you want to split or customize virtual appointment interactions from day-to-day employee Teams activity.

Extend Microsoft 365 with Azure

The rest of this tutorial focuses on Microsoft 365 and Azure hybrid solutions. These hybrid configurations are popular because they combine employee familiarity of Microsoft 365 with the ability to customize the consumer experience. They’re also a good launching point to understanding more complex and customized architectures. The diagram below shows user steps for a virtual appointment:

1. Consumer schedules the appointment using Microsoft 365 Bookings.
2. Consumer gets an appointment reminder through SMS and Email.
3. Provider joins the appointment using Microsoft Teams.
4. Consumer uses a link from the Bookings reminders to launch the Contoso consumer app and join the underlying Teams meeting.
5. The users communicate with each other using voice, video, and text chat in a meeting. Specifically, Teams chat interoperability enables Teams user to send inline images or file attachments directly to Azure Communication Services users seamlessly.

Building a virtual appointment sample

In this section, we’re going to use a Sample Builder tool to deploy a Microsoft 365 + Azure hybrid virtual appointments application to an Azure subscription. This application is a desktop and mobile friendly browser experience, with code that you can use to explore and for production.

Step 1: Configure bookings

This sample uses takes advantage of the Microsoft 365 Bookings app to power the consumer scheduling experience and create meetings for providers. Thus the first step is creating a Bookings calendar and getting the Booking page URL from https://outlook.office.com/bookings/calendar.

Make sure online meeting is enabled in the calendar by going to https://outlook.office.com/bookings/services.

And then make sure "Add online meeting" is enabled.

Step 2: Sample Builder

Use the Sample Builder to customize the consumer experience. You can reach the Sampler Builder using this link or navigating to the page within the Azure Communication Services resource in the Azure portal. Step through the Sample Builder wizard: select Industry template, configure the call experience (Chat or Screen Sharing availability), change themes and text to match your application style and get valuable feedback through post-call survey options. You can preview your configuration live from the page in both Desktop and Mobile browser form-factors.

Step 3: Deploy

At the end of the Sample Builder wizard, you can Deploy to Azure or download the code as a zip. The sample builder code is publicly available on GitHub.

The deployment launches an Azure Resource Manager (ARM) template that deploys the themed application you configured.

After walking through the ARM template, you can Go to resource group.

Step 4: Test

The Sample Builder creates three resources in the selected Azure subscriptions. The App Service is the consumer front end, powered by Azure Communication Services.

Opening the App Service’s URL and navigating to https://<YOUR URL>/VISIT allows you to try out the consumer experience and join a Teams meeting. https://<YOUR URL>/BOOK embeds the Booking experience for consumer scheduling.

Step 5: Set deployed app URL in Bookings

Enter the application url followed by "/visit" in the "Deployed App URL" field in https://outlook.office.com/bookings/businessinformation.

Going to production

The Sample Builder gives you the basics of a Microsoft 365 and Azure virtual appointment: consumer scheduling via Bookings, consumer joins via custom app, and the provider joins via Teams. However, there are several things to consider as you take this scenario to production.

Launching patterns

Consumers want to jump directly to the virtual appointment from the scheduling reminders they receive from Bookings. In Bookings, you can provide a URL prefix that is used in reminders. If your prefix is https://<YOUR URL>/VISIT, Bookings point users to https://<YOUR URL>/VISIT?MEETINGURL=<MEETING URL>.

Integrate into your existing app

The app service generated by the Sample Builder is a stand-alone artifact, designed for desktop and mobile browsers. However you may have a website or mobile application already and need to migrate these experiences to that existing codebase. The code generated by the Sample Builder should help, but you can also use:

• UI SDKs – Production Ready Web and Mobile components to build graphical applications.
• Core SDKs – The underlying Call and Chat services can be accessed and you can build any kind of user experience.

Identity & security

The Sample Builder’s consumer experience doesn't authenticate the end user, but provides Azure Communication Services user access tokens to any random visitor. That isn’t realistic for most scenarios, and you want to implement an authentication scheme.

Customizations

Kindly be aware that the code sample presented here is intended as a foundation for your virtual appointments application. It is crucial to understand that adjustments tailored to your unique use case will be essential. We recommend reviewing the code, making the necessary modifications, and referring to the accompanying documentation for assistance.
