EWS exception while trying to read email from exchange

I am facing an issue while reading emails from my exchange email account using EWS Microsoft API.

Please help me with a solution if anybody has

Used below code

static void Main(string[] args)

{

string UserName = "**";

string Password = "**";

string EXCHANGEMAILURL = @"";

ExchangeService service = new ExchangeService();

service.Timeout = 500000;

service.Credentials = new NetworkCredential(UserName, Password);

service.Url = new Uri(EXCHANGEMAILURL);

try

{

ServicePointManager.SecurityProtocol = (SecurityProtocolType)3072;

ServicePointManager.ServerCertificateValidationCallback += (sender, certificate, chain, sslPolicyErrors) => true;

FindFoldersResults folderSearchResults = service.FindFolders(WellKnownFolderName.MsgFolderRoot, new FolderView(int.MaxValue));

Folder xChangeSourceFolder = folderSearchResults.Folders.ToList().Find(

f => f.DisplayName.Equals("Inbox", StringComparison.CurrentCultureIgnoreCase));

ItemView itemView = new ItemView(50);

FindItemsResults findIncomingMails = service.FindItems(xChangeSourceFolder.Id, new SearchFilter.IsEqualTo(EmailMessageSchema.IsRead, false),

new ItemView(50));

Item item = findIncomingMails.First();

EmailMessage messageHTML = (EmailMessage)item;

messageHTML.Load(new PropertySet(BasePropertySet.FirstClassProperties, ItemSchema.Attachments, ItemSchema.Body) { RequestedBodyType = BodyType.HTML });

string htmlString = messageHTML.Body.Text.ToString();

}

catch (Exception ex)

{

Console.WriteLine("Exception Occurred : " + ex.StackTrace);

}

The exception

Unable to connect to the remote server

Hi Ajit,

It looks like you are experiencing a connection issue when trying to access your Exchange email account using the EWS (Exchange Web Services) API. Here are a few things you can try to troubleshoot and resolve the issue:

Verify that the URL you are using to connect to the Exchange server is correct and working. You can try accessing the URL in a web browser to see if it is accessible.
Check that your credentials (username and password) are correct and that you have the necessary permissions to access the Exchange server.
Check that your network connection is stable and that you are able to connect to other websites.
If you are using a proxy server to connect to the Exchange server, make sure that the proxy settings are correct and that the proxy is not blocking your connection.
If you are using a VPN to connect to the Exchange server, make sure that the VPN connection is stable and that you are able to connect to other websites.
If you are behind a firewall, make sure that the firewall is not blocking your connection to the Exchange server.
If you are still experiencing issues after trying the above steps, you may want to try increasing the timeout value in your code. You can do this by setting the service.Timeout property to a higher value, such as 1000000 (1 second).
