Tracking Microsoft 365 Outlook Email to SQL Server

I want to fetch the details from my outlook mailbox but don't have the Microsoft exchange server. I only have cloud-based services.
I tried to use the below-given code but that is an exchange server API solution. The second method is to open the outlook app and then accessing the mailbox but doesn't want this solution.
try
{
'Mailbox credentials'
string emailAddress = AppSettings.Office365EmailAddress;
string password = AppSettings.Office365Password;
ServicePointManager.ServerCertificateValidationCallback =
CertificateValidationCallBack;
ExchangeService service = new
ExchangeService(ExchangeVersion.Exchange2013_SP1);
service.Credentials = new WebCredentials(emailAddress, password);
service.Url = new Uri("https://outlook.office365.com/EWS/Exchange.asmx");
service.PreAuthenticate = true;
service.ImpersonatedUserId = new ImpersonatedUserId(ConnectingIdType.SmtpAddress,
emailAddress);
ItemView view = new ItemView(int.MaxValue);
FindItemsResults<Item> findResults = service.FindItems(WellKnownFolderName.Inbox,
SetFilter(), view);
DataTable dtEmails = GenerateEmailDataTable();
DataRow dr = dtEmails.NewRow();
foreach (Item item in findResults.Items)
{
if (item.Subject != null)
{
Match match = Regex.Match(item.Subject.ToString(), regJMSNumber);
if (match != null)
{
dr["EmailTo"] = item.DisplayTo.ToString();
dr["EmailFrom"] = item.DisplayTo.ToString();
dr["EmailCC"] = item.DisplayCc.ToString();
dr["EmailBCC"] = item.DisplayTo.ToString();
dr["EmailSubject"] = item.Subject.ToString();
dr["EmailBody"] = item.Body.ToString();
dr["CreatedOn"] = item.Subject.ToString();
dr["IsActive"] = true;
}
else
{
Console.WriteLine("Subject Not Match");
}
}
}
}
'Error handler.'
catch (System.Exception e)
{
Console.WriteLine("{0} Exception caught: ", e);
}
finally
{
}
Another approach is the Power Automate option but I want to do it programmatically.
Used https://outlook.office365.com/EWS/Exchange.asmx API.
When I am using EWS (exchange API), the application throwing a 401 Unauthorised requests failed exception.
Please tell me any other way to track the outlook emails with all details like EmailTo, EmailSent, EmailSubject, EmailBody, EmailCC, EmailBCC, and all the trailing messages.

Mailkit is sending emails with the incorrect from address

I've written a mail method and I'm setting the from email address but when the customer receives it, it's the same as the username that is used to authenticate the email.
I've tried to set the email right before the send and it still comes out wrong:
When I check the message, as shown above, the from is correct but the customer receives it from the username field instead.
public static EmailResults SendEmail(EmailSettings emailSettings)

Anyone have any suggestions on what I'm doing wrong?

For anyone who runs in to this again...
This particular issue is specific to Gmail. I'm not sure if other email hosts do the same.
If you are setting the from email address to "person1#email.com" but authenticating with "person2#gmail.com", Gmail will override the from email address with the authentication email address. You have no control over this.

Go to the Gmail account, into settings, and add the alias address in the "Send Mail As" section. The outgoing email should now display with the alias address rather than the authenticating address.

Remembering log in credentials/permissions UWP/C# (Microsoft Cloud API)

I'm creating an app that access the Microsoft Cloud API to get health data. It uses OAuth to log in when you hit the Sign In Button
private void signinButton_Click(object sender, RoutedEventArgs e)
{
UriBuilder uri = new UriBuilder("https://login.live.com/oauth20_authorize.srf");
var query = new StringBuilder();
query.AppendFormat("redirect_uri={0}", Uri.EscapeDataString(RedirectUri));
query.AppendFormat("&client_id={0}", Uri.EscapeDataString(ClientId));

query.Append("&response_type=code");
uri.Query = query.ToString();
this.webView.Visibility = Visibility.Visible;
this.webView.Navigate(uri.Uri);
}
This brings up a webView with the page to log in using Microsoft credentials. Once completed, it leads to this:
private async void WebView_NavigationCompleted(WebView sender, WebViewNavigationCompletedEventArgs args)
{
//
// When the web view navigates to our redirect URI, extract the authorization code from
// the URI and use it to fetch our access token. If no authorization code is present,
// we're completing a sign-out flow.
//
if (args.Uri.LocalPath.StartsWith("/oauth20_desktop.srf", StringComparison.OrdinalIgnoreCase))
{
WwwFormUrlDecoder decoder = new WwwFormUrlDecoder(args.Uri.Query);
var code = decoder.FirstOrDefault((entry) => entry.Name.Equals("code", StringComparison.OrdinalIgnoreCase));
var error = decoder.FirstOrDefault((entry) => entry.Name.Equals("error", StringComparison.OrdinalIgnoreCase));
var errorDesc = decoder.FirstOrDefault((entry) => entry.Name.Equals("error_description", StringComparison.OrdinalIgnoreCase));
// Check the code to see if this is sign-in or sign-out
if (code != null)
{
// Hide the browser again, no matter what happened...
sender.Visibility = Visibility.Collapsed;
if (error != null)
{
this.responseText.Text = string.Format("{0}\r\n{1}", error.Value, errorDesc.Value);
return;

}
}
I don't want users to have to accept the permissions every time the app is launched. Is there a way to save credentials locally so that it automatically authenticates on launch? Thanks!

You can use
Windows.Storage.ApplicationData.Current.LocalSettings
This process good described by this answer Best Way to keep Settings for a WinRT App?
The code in link identity to UWP

Store the needed oauth parts in the credential locker API. Never store these kind of information in the normal settings API.
On start read the oauth information and use the refreshtoken to get a new access token.

MailChimp Integaration with MVC 5

I am working on an MVC5 project, the client is interested in using MailChimp for sending emails. I have explored the MailChimp and wrappers ( MailChimp.NET ) and tried in my project as well. I tested the REST API as well and it seems to work , for example; I was able to grab lists and templates using REST API. But, still I am having issues with sending email through MailChimp.
So far, I have tried the following code and its working. Now I want to send an email to a newly registered user. Kindly give me detailed code example that How can I achieve this, because I am totally struck here..
var apiKey = "myapikey-us11";
var listId = "mylistid";
var subscribeRequest = new
{
apikey = apiKey,
id = listId,
email = new
{
email = "muhammad.waqas#seventechnology.co.uk"
},
double_optin = true,
};
var requestJson = JsonConvert.SerializeObject(subscribeRequest);
var reqresult = CallMailChimpApi("lists/", requestJson);
CallMailChimApi
private static string CallMailChimpApi(string method, string requestJson)
{
var endpoint = String.Format("https://{0}.api.mailchimp.com/3.0/{1}", "us11", method);
var wc = new WebClient();
try
{
return wc.UploadString(endpoint, requestJson);
}
catch (WebException we)
{
using (var sr = new StreamReader(we.Response.GetResponseStream()))
{
return sr.ReadToEnd();
}
}
}

I Use this function and it work successfully
public void SendEmailByApiMailChimp ()
{
try
{
string UserEmail = " Exemple#gmail.com ";
MailChimpManager mc = new MailChimpManager("16d***********-us14");
EmailParameter email = new EmailParameter()
{
Email = UserEmail
};
