Setting up and administering Microsoft Exchange is a crucial part of getting your email and calendar systems up and running. To start, you'll need to install the Microsoft Exchange Server software on your server.
The installation process typically takes about 30 minutes to an hour, depending on your server's configuration and internet connection speed. Once installed, you'll need to configure the server settings, including setting up the domain name and mailboxes.
You'll also need to configure the Exchange server to integrate with your existing Active Directory. This will allow users to log in to their mailboxes with their existing Active Directory credentials.

Your IT admin will usually take care of the setup process if you're part of an organization. This way, you can focus on using the application without worrying about the technical details.
To get started with Exchange Online, you'll need to purchase a subscription to Microsoft 365 that includes this service.
Architecture and Components
In a Microsoft Exchange application, the architecture and components play a crucial role in its functionality.
Client Access Servers are only visible in the Exchange on-premises architecture and are a load-balanced group of servers that authenticate requests and proxy received requests to the Mailbox server.
Individual Client Access Servers are thin and stateless, meaning they cannot store or queue data or do any data rendering, requiring a CAS server and load balancer to perform these activities.

Web Services Architecture
The EWS architecture is designed to work with both on-premises and online versions of Microsoft Exchange. It's a key part of the EWS architecture.
The architecture includes several important elements, such as the Client Access Server (CAS) and the load balancer. These components are only visible in the Exchange on-premises architecture.
The CAS is a load-balanced group of servers that authenticate requests, perform Exchange Autodiscover lookups, and proxy received requests to the Mailbox server. They're thin and stateless, meaning they can't store or queue data or do any data rendering.
In the EWS architecture, the load balancer distributes the SOAP/XML message to a CAS in the CAS array. This helps to ensure that the system is scalable and can handle a large number of requests.
The EWS service is described by three files and EWS Managed API assemblies (EWS on-premises architecture only). Each file has its own function, including describing the contract between the client and server, defining the request and response SOAP messages, and defining the elements used in the SOAP messages.
The API assemblies are provided for server-side EWS client applications and are deployed on all Exchange Server roles. The EWS schemas are backward- and forward-compatible, so an application that targets an earlier schema version will also work with a later schema version.
Here's a quick rundown of the key components in the EWS architecture:
- CAS: Client Access Server, responsible for authenticating requests and proxying requests to the Mailbox server
- Load balancer: distributes SOAP/XML messages to a CAS in the CAS array
- EWS service: described by three files and EWS Managed API assemblies
Ews Service
The EWS service is described by three files and EWS Managed API assemblies. These files are not used for schema validation, but the EWS schemas are backward- and forward-compatible, so an application that targets an earlier schema version will also work with a later schema version.
The three files are responsible for describing the contract between the client and server, defining the request and response SOAP messages, and defining the elements used in the SOAP messages.
The EWS Managed API assemblies are provided for server-side EWS client applications and deployed on all Exchange Server roles.

Server vs Cloud Server
The primary difference between a server and a cloud server lies in their deployment models. Exchange Server, for instance, is an on-premises solution that organizations install and manage within their own IT infrastructure.
Exchange Server offers full control over the email environment, including the Windows server hardware, software, and data storage. This level of control requires significant upfront investment and ongoing maintenance.

Exchange Online, on the other hand, is hosted on Microsoft's cloud servers and is managed remotely through a web-based admin interface. Microsoft is responsible for the upkeep, security, and reliability of the service.
A significant upfront investment is needed for Exchange Server, whereas Exchange Online operates on a subscription model. This means organizations can save on initial costs and focus on other aspects of their business.
Continuous updates and integrations with other cloud services within the Microsoft ecosystem are also a benefit of Exchange Online. This ensures the service stays up-to-date and secure without requiring manual updates.

Set Up Autodiscover URL Redirection Validation
To trust and follow Autodiscover redirects, you need to set up URL redirection validation. This is achieved by adding a redirection validation callback method to your code.
The validation callback method is used to validate whether redirected URLs returned by Autodiscover represent an HTTPS endpoint. In a simple validation callback, the redirection URL is considered valid if it's using HTTPS to encrypt authentication credentials.
You can add the following redirection validation callback method to your code:
```html
- Add the following redirection validation callback method after the Main(string[] args) method.
- private static bool RedirectionUrlValidationCallback(string redirectionUrl)
- { // The default for the validation callback is to reject the URL.
- bool result = false;
- Uri redirectionUri = new Uri(redirectionUrl);
- // Validate the contents of the redirection URL.
- // In this simple validation callback, the redirection URL is considered valid if it is using HTTPS
- // to encrypt the authentication credentials.
- if (redirectionUri.Scheme == "https")
- { result = true; }
- return result;
```
This validation callback will be passed to the ExchangeService object in step 4 of the Autodiscover process. This ensures that your application trusts and follows Autodiscover redirects, which provides the EWS endpoint for your application.
In an Exchange on-premises architecture, Autodiscover redirects are handled by a Client Access Server (CAS). A CAS is a load-balanced group of servers that authenticate requests, perform Exchange Autodiscover lookups, and proxy received requests to the Mailbox server.
Administering
As an admin, you'll use the Exchange admin center (EAC) to manage the organization's Exchange Online service.
The EAC is a web-based interface that allows you to perform administrative tasks, such as setting up new users, configuring mail flow, and managing security settings.
You can also use the Microsoft 365 admin center for simpler tasks, such as basic email and user management.
This makes it easier to manage your organization's email and calendar services without having to navigate multiple interfaces.
Suggestion: Onedrive Admin Center
To access the EAC, you'll need to sign in with your organizational credentials, just like you would to access your email.
If you're managing Exchange Online yourself, you'll need to purchase a subscription to Microsoft 365 that includes Exchange Online, or get it as a standalone service.
As an admin, it's essential to have a good understanding of the Exchange Online service and its features, so you can effectively manage and troubleshoot issues.
By using the EAC and Microsoft 365 admin center, you'll be able to efficiently manage your organization's email and calendar services, and ensure that everything runs smoothly.

Development and Integration
To develop applications for Microsoft Exchange, you can use the Exchange Web Services (EWS) in a couple of different ways. The simplest way is to create text files containing your XML requests and transmit them to Exchange.
You'll need a simple text editor, like Notepad, to edit your XML request, and a tool or application that can send and receive SOAP XML requests and responses. A basic understanding of XML formatting is also helpful.
A fresh viewpoint: Microsoft Xml Core Services
If you prefer to use a .NET language like C#, you can create an autogenerated proxy to work with the operations. This requires Visual Studio 2005 or later and the .NET Framework 2.0 or later.
Here are the tools and technologies you'll need to get started with EWS:
- A simple text editor, like Notepad
- A tool or application that can send and receive SOAP XML requests and responses
- Visual Studio 2005 or later
- The .NET Framework 2.0 or later
If you're a .NET Framework developer, we encourage you to use the EWS Managed API, which is easier to use than autogenerated proxy object models. It also implements Autodiscover and includes client-side logic.
Create First Managed API App
To create your first EWS Managed API application, you'll need to set up an Office 365 Developer Site. This will save you time in the long run.
The steps to create your first application assume you've already set up your Office 365 Developer Site. If you've downloaded and installed Exchange, be aware that you'll need to install a valid certificate on your Exchange server.
You'll also need to implement a certificate validation callback for a self-signed certificate that's provided by default. This is a crucial step to ensure your application runs smoothly.

The version of Visual Studio you're using might affect the steps slightly, so keep that in mind as you proceed. Don't worry, it's not a major hurdle.
To get started, add your code to the Program.cs file. This is where you'll develop the basic code to write most EWS Managed API client applications.
EWS Development Environment
To set up a development environment for EWS, you'll need a few things. You can start by creating text files that contain your XML requests and transmitting them to Exchange. To do this, you'll need a simple text editor, like Notepad, to edit your XML request.
You'll also need a tool or application that can send and receive SOAP XML requests and responses, in order to communicate with Exchange. Having a basic understanding of XML formatting can be helpful as well.
Alternatively, you can create an autogenerated proxy that enables you to work with the operations by using a .NET language like C#. To do this, you'll need a version of Visual Studio starting with Visual Studio 2005, and a version of the .NET Framework starting with the .NET Framework 2.0.
Suggestion: Azure Visual Studio
If you're a .NET Framework developer, you're encouraged to use the EWS Managed API rather than autogenerated proxies to develop against EWS. The EWS Managed API object model is easier to use than autogenerated proxy object models, and it implements Autodiscover and includes client-side logic.
Here are the requirements for setting up a development environment for EWS:
- A simple text editor, like Notepad, to edit your XML request
- A tool or application that can send and receive SOAP XML requests and responses
- A version of Visual Studio starting with Visual Studio 2005
- A version of the .NET Framework starting with the .NET Framework 2.0
- Basic understanding of XML formatting
You can choose the method that works best for you, and get started with developing your EWS application.
