My problem:
The same code works fine in one instance but cannot authenticate with same username/password in another instance of the project.
My code:
static NetworkCredential _emailLoginCredentials;
_emailLoginCredentials = new NetworkCredential(_accountName, _accountPassword, _accountDomain);
using (var client = new ImapClient(new ProtocolLogger("C://Temp//Logs//imap1.log")))
{
var credentials = _emailLoginCredentials;
var uri = new Uri(_emailServer);
string serverReply = String.Empty;
client.Timeout = _imapClientTimeOut;
client.Connect(uri);
client.AuthenticationMechanisms.Remove("XOAUTH2");
client.Authenticate(credentials);
client.Inbox.Open(FolderAccess.ReadWrite);
}
Error:

To troubleshoot, I even hard-coded username and password in both. However, the outcome is still the same - one working and the other not working.
Well, there are some differences in the project setup etc. For example, in the non-working project, I am using above authentication code within a Mutex. Also, the entire method is protected override async Task Process(TaskMessage message)
Found this post but it was caused by NTLM which is not related to my case.
Plain authentication contains two or three strings: "I wish to log in as x, I'm actually y, and my password is z". The two common cases are x=y and x not specified. Very rarely, y is a super-duper-privileged administrative user that can log in as others.
In your working case, x is empty and y is xCaratsdev. In your error case, x is gicnt. Your password is the same in both cases (it's in the base64 blobs). Your next job is to find out where that gicnt comes from. But first, change the password.
