We are using Rebex 2016 R3 POP3- 2.0.6198.0 version.
We are facing issue with POP3 whereas IMAP is able to connect to office365.
For pop3 facing a following exception:
A connection attempt failed because the connected party did not
properly respond after a period of time, or established connection
failed because connected host has failed to respond.
Our dummy code is: this is not production but just a simple test connection code.
var client = new Pop3();
client.Settings.SslAllowedVersions = TlsVersion.Any;
client.ValidatingCertificate += new EventHandler<SslCertificateValidationEventArgs>(ValidateCertificate);
client.Settings.SslAcceptAllCertificates = true;
Do we missing anything for pop3?
