Unable to connect to outlook 365 via Imap

0 votes

I just downloaded limilabs mail to try out to use imap to connect to outlook 365. It seems not getting any response. When I ping the outlook.office365.com from command prompt, it got response. Not sure what goes wrong. Please help if you have any idea. Thanks!

Sub Main()
    Console.WriteLine("Starting...")

    Using imap As New Imap
        Console.WriteLine("Connecting...")
        imap.ConnectSSL("outlook.office365.com", 993)
        Console.WriteLine("Connected...")

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

I just checked, and I have no problems connecting. Please check your firewall settings.

Here's my code:

using (Imap imap = new Imap())
{
    imap.ConnectSSL("outlook.office365.com");

    imap.Close();
}

....and the logs:

I also tried using this IP address - no problems (apart from an obvious certificate error, as the connection was done using IP address and not DNS name).
