How to Use MS-Graph to Remove Email from a Subfolder

Using C# to Remove Specific Emails from an MS Graph

Implementation of the Microsoft Graph API with C#

using Microsoft.Graph;
using System.Threading.Tasks;
// Define asynchronous method to delete an email
public async Task DeleteEmailFromSubfolder(GraphServiceClient graphClient, string userPrincipalName, string subFolderId, string messageId)
{
    try
    {
        // Construct the request to access subfolder directly
        var request = graphClient.Users[userPrincipalName].MailFolders[subFolderId].Messages[messageId].Request();
        // Execute delete operation
        await request.DeleteAsync();
        Console.WriteLine("Email deleted successfully from subfolder.");
    }
    catch (ServiceException ex)
    {
        Console.WriteLine($"Error deleting email: {ex.Message}");
    }
}

Advanced MS Graph and C# Techniques

using Microsoft.Graph;
using System.Threading.Tasks;
// Helper function to find the right subfolder and delete the message
public async Task DeleteEmailCorrectly(GraphServiceClient graphClient, string userPrincipalName, string parentFolderName, string subFolderId, string messageId)
{
    try
    {
        // Retrieve the child folders under the Inbox
        var childFolders = await graphClient.Users[userPrincipalName].MailFolders[parentFolderName].ChildFolders.Request().GetAsync();
        var subFolder = childFolders.FirstOrDefault(f => f.Id == subFolderId);
        if (subFolder != null)
        {
            // Directly delete the message if the folder is correctly identified
            await graphClient.Users[userPrincipalName].MailFolders[subFolder.Id].Messages[messageId].Request().DeleteAsync();
            Console.WriteLine("Successfully deleted the email from the specified subfolder.");
        }
        else
        {
            Console.WriteLine("Subfolder not found.");
        }
    }
    catch (ServiceException ex)
    {
        Console.WriteLine($"Error: {ex.Message}");
    }
}
