@albertose,
Thank you for contacting support.

Please enable activity logging as shown here (use the same way for EWS) and share the following:

  • generated log file
  • code example or a simple project reproducing the errors

Hi Andrey,

here’s the code sample:

string serviceUrl = "https://outlook.office365.com/EWS/Exchange.asmx";
string username = "test@test.onmicrosoft.com";
string password = "*******";

ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls | SecurityProtocolType.Tls11 | SecurityProtocolType.Tls12 | SecurityProtocolType.Ssl3;

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

var service = EWSClient.GetEWSClient(serviceUrl, username, password);

Generated logs show the same error message.

@albertose,
Thank you for the additional information. We will reply to you as soon as possible.

@albertose,
Unfortunately, I was unable to reproduce the error you described. This code example works fine from my end. It would be great if you could share test credentials with us. The log file mentioned above is also important.
