Answer 1

Hi @SAC_535

I wrote a C# sample for you that gets the details of a message by message id. I'm using the client credential flow to get the token, before that you need to grant the Mail.ReadBasic.All application permission to your application.

using Microsoft.Graph;  
using Microsoft.Graph.Auth;  
using Microsoft.Identity.Client;  
using Newtonsoft.Json;  
  
  
namespace test1  
  
{  
    class Program  
    {  
        static async System.Threading.Tasks.Task Main(string[] args)  
        {  
  
            IConfidentialClientApplication app;  
            app = ConfidentialClientApplicationBuilder.Create("{client id}")  
                    .WithClientSecret("{client secret}")  
                    //.WithRedirectUri("https://jwt.ms")  
                    .WithAuthority(new Uri("https://login.microsoftonline.com/{tenant id}"))  
                    .Build();  
  
            AuthenticationResult result;  
  
            string[] scopes = new string[] { "https://graph.microsoft.com/.default" };  
  
            result = await app.AcquireTokenForClient(scopes).ExecuteAsync();  
  
            /*string accesstoken = result.AccessToken;  
      
            Console.WriteLine(accesstoken);*/  
  
            ClientCredentialProvider authProvider = new ClientCredentialProvider(app);  
  
            GraphServiceClient graphClient = new GraphServiceClient(authProvider);  
  
            var message = await graphClient.Users["{user id}"].Messages["{message id}"]  
    .Request()  
    .GetAsync();  
  
            Console.WriteLine("message:" + JsonConvert.SerializeObject(message));  
  
        }  
    }  
}

Hi @SAC_535

It will indeed return multiple messages if the subject is the same. After my research found a better way, you can use internetMessageId to filter the information of the message, MessageId is specific and you can use it to get the complete information of the message.

Follow the procedure below:

1.Double-click an email message to open it outside of the Reading Pane.
2.Click Tags>arrow symbol.

https://graph.microsoft.com/v1.0/me/messages?$filter=internetMessageId eq '{Message id}'
