    If you are trying to get the messages with C# code , you should try with below code

    GraphServiceClient graphClient = new GraphServiceClient( authProvider );  
      
    var message = await graphClient.Me.Messages["{message-id}"]  
    	.Request()  
    	.GetAsync();  
    

    Ref doc - https://learn.microsoft.com/en-us/graph/api/message-get?view=graph-rest-1.0&tabs=csharp

    Git - https://github.com/microsoftgraph/microsoft-graph-docs/blob/main/api-reference/beta/api/user-list-messages.md

    Hope this helps

    Thanks

    Hi @SAC_535

    You can call the endpoint using the C# Graph SDK, and since /users/{user id} only supports application contexts, you need to use the client credentials flow to get a token. Please refer to the complete code:

    using Azure.Identity;   
    using Microsoft.Graph;  
    using Newtonsoft.Json;  
          
    var scopes = new[] { "https://graph.microsoft.com/.default" };  
      
    var tenantId = "{tenant id}";  
      
    // Values from app registration  
    var clientId = " {client id}";  
    var clientSecret = "{client secret}";  
      
    // using Azure.Identity;  
    var options = new TokenCredentialOptions  
    {  
        AuthorityHost = AzureAuthorityHosts.AzurePublicCloud  
    };  
      
    // https://learn.microsoft.com/dotnet/api/azure.identity.clientsecretcredential  
    var clientSecretCredential = new ClientSecretCredential(  
        tenantId, clientId, clientSecret, options);  
      
    var graphClient = new GraphServiceClient(clientSecretCredential, scopes);  
      
    var message = await graphClient.Users["{user id}"].Messages["{message id}"]  
          .Request()  
          .GetAsync();  
      
    Console.WriteLine("message:" + JsonConvert.SerializeObject(message));
