I am converting generic mailboxes to exchange online. I am doing some operation and then forwarding that mail to another mail.

I have Mail.ReadWrite and Mail.Send API permissions. But still getting exception of type 'microsoft.graph.models.odata errors.odata error' was thrown.'. Please suggest me on this.

Don't have User.Read permission is that causing me an issue.

Hi @Hattikoti, Roopa S

I can't find the problem from the type of exception you shared, you should catch the error message to analyze the problem details.

Please refer to my code snippet:

try {
    var requestBody = new Microsoft.Graph.Me.Messages.Item.Forward.ForwardPostRequestBody
    {
        Comment = "comment-value",
        ToRecipients = new List<Recipient>
    {
        new Recipient
        {
            EmailAddress = new EmailAddress
            {
                Name = "name-value",
                Address = "address-value",
            },
        },
    },
    };
    await graphClient.Me.Messages["{message id}"].Forward.PostAsync(requestBody);
}
catch (ODataError odataError)
{

    Console.WriteLine(odataError.Error.Code);
    Console.WriteLine("Error Message: " + odataError.Error.Message);

}

Got the above error message. Please suggest me on this.

Hi @Hattikoti, Roopa S

The /me endpoint only supports delegated authentication flows, such as auth code flow or ROPC flow.

It looks like you're using the client credentials flow for authentication, which is what's causing the problem. Please change the /me endpoint to the /users/{user id} endpoint:

var requestBody = new Microsoft.Graph.Users.Item.Messages.Item.Forward.ForwardPostRequestBody
{
	Comment = "comment-value",
	ToRecipients = new List<Recipient>
	{
		new Recipient
		{
			EmailAddress = new EmailAddress
			{
				Name = "name-value",
				Address = "address-value",
			},
		},
	},
};
await graphClient.Users["{user-id}"].Messages["{message-id}"].Forward.PostAsync(requestBody);

If you must use the /me endpoint, then use the delegated authentication flow to obtain an access token.

var scopes = new[] { "Mail.Send" };

var tenantId = "TENANT_ID";

// Values from app registration
var clientId = "YOUR_CLIENT_ID";
var clientSecret = "YOUR_CLIENT_SECRET";

// For authorization code flow, the user signs into the Microsoft
// identity platform, and the browser is redirected back to your app
// with an authorization code in the query parameters
var authorizationCode = "AUTH_CODE_FROM_REDIRECT";

// using Azure.Identity;
var options = new AuthorizationCodeCredentialOptions
{
    AuthorityHost = AzureAuthorityHosts.AzurePublicCloud,
};

// https://learn.microsoft.com/dotnet/api/azure.identity.authorizationcodecredential
var authCodeCredential = new AuthorizationCodeCredential(
    tenantId, clientId, clientSecret, authorizationCode, options);

var graphClient = new GraphServiceClient(authCodeCredential, scopes);
