How to acces your o365 mail via c

To access your Office 365 (O365) mail via C#, you'll need to use the Microsoft Graph API or the EWS (Exchange Web Services) API. Here's a step-by-step guide to help you get started:

Option 1: Microsoft Graph API

Register your application: Go to the Azure portal (https://portal.azure.com/) and register your application. You'll need to create a new Azure AD application and grant the necessary permissions.
Install the Microsoft Graph SDK: Install the Microsoft Graph.NET Client Library NuGet package: Microsoft.Graph
Get an access token: Use the client ID and client secret to obtain an access token. You can do this using the Microsoft.Identity.Client NuGet package.
Use the Microsoft Graph API: Use the access token to call the Microsoft Graph API to retrieve your email messages. You can use the Microsoft.Graph.Mail namespace to interact with your email.

Here's some sample C# code to get you started:

using Microsoft.Graph;
using Microsoft.Identity.Client;

// Replace with your app's client ID and client secret
string clientId = "your_client_id";
string clientSecret = "your_client_secret";
string tenantId = "your_tenant_id";

// Get an access token
var app = ConfidentialClientApplicationBuilder.Create(clientId)
   .WithClientSecret(clientSecret)
   .WithTenantId(tenantId)
   .Build();

var tokenAcquisitionResult = await app.AcquireTokenSilentAsync(scopes: new[] { "https://graph.microsoft.com/.default" });
string accessToken = tokenAcquisitionResult.AccessToken;

// Use the access token to call the Microsoft Graph API
var graphClient = new GraphServiceClient(new DelegateAuthenticationProvider((requestMessage) =>
{
    requestMessage.Headers.Authorization = new AuthenticationHeaderValue("Bearer", accessToken);
    return Task.CompletedTask;
}));

// Retrieve your email messages
var messages = await graphClient.Me.MailFolders.Inbox.Messages.Request().GetAsync();

Option 2: EWS API

Install the EWS Managed API: Install the EWS Managed API NuGet package: Microsoft.Exchange.WebServices
Create an EWS connection: Create an instance of the ExchangeService class and set the necessary properties (e.g., URL, username, password).
Use the EWS API: Use the ExchangeService instance to interact with your email.

Here's some sample C# code to get you started:

using Microsoft.Exchange.WebServices.Data;

// Replace with your email address and password
string username = "your_email_address";
string password = "your_password";

// Create an EWS connection
ExchangeService service = new ExchangeService();
service.Url = new Uri("https://outlook.office365.com/EWS/Exchange.asmx");
service.Credentials = new WebCredentials(username, password);

// Retrieve your email messages
FindItemsResults<Item> findResults = service.FindItems(new ItemView(10));
foreach (Item item in findResults.Items)
{
    Console.WriteLine(item.Subject);
}

Remember to replace the placeholders with your actual O365 credentials and settings.
