IMAP and POP are two methods to access email. IMAP is the recommended method when you need to check your emails from several different devices, such as a phone. Configuring the TLS Certificate Name for Exchange Server Receive Connectors. Consider a scenario in which youre trying to do the right thing by ensuring that authenticated SMTP client connections to your Exchange server are protected by TLS encryption. Most commonly this will be when you have IMAP or POP clients configured with the Exchange server or a DNS alias that points to the Exchange server as the SMTP server for sending email. If the client tries to authenticate over an unencrypted connection, a message is received with words to the effect of The outgoing server SMTP mail. After Googling around you learn that your SMTP client should use STARTTLS in order to authenticate securely. Heres an example of how that is configured in Mozilla Thunderbirds outgoing server settings. Notice also the use of port 5. Techbytes/files/2014/03/Thunderbird_mail_server_setup.png' alt='Set Up Microsoft Exchange Server Email Thunderbird Vs Gmail' title='Set Up Microsoft Exchange Server Email Thunderbird Vs Gmail' />Exchange servers are pre configured by setup with a receive connector that is designed for use by SMTP clients, named SERVERNAMEClient Frontend SERVERNAME. This is the port and connector that you should be using for your authenticated SMTP clients. When you next attempt to send an email you get a different error. Depending on the email client you may get a certificate trust warning, a prompt to add a security exception to trust the untrusted certificate, or it may just fail completely with a certificate error. In all cases, clearly something is still not right. The solution here is in the configuration of the receive connector that authenticated SMTP clients will be connecting to. Even though you have enabled a valid SSL certificate for SMTP, the connector needs to be configured with the TLS certificate name that you want to use. The first time I ran into this problem I found lots of articles and blog posts telling me that was the solution, but none of them told me how to actually configure that. And if you look at the Set Receive. Connector documentation, you still get confusing and wrong advice. The Tls. Certificate. Name parameter specifies the X. TLS sessions and secure mail. Valid input for this parameter is IIssuerSSubject. The Issuer value is found in the certificates Issuer field, and the Subject value is found in the certificates Subject field. You can find these values by running the Get Exchange. Certificate cmdlet. The above would probably be more useful if it provided an example, but more importantly, the I and S are not correct. If you try to use them, your Set Receive. Connector command will fail. Heres an example of using the correct syntax for Tls. Certificate. Name. First, determine the thumbnail value for the certificate you want to use. In this example Im going to use my wildcard certificate, which is already enabled for SMTP. PS C Get Exchange. Certificate.

How are you trying to login to webmail Are you going to your domain name followed by webmail such as http example. If you arent able to login to webmail, chances are a desktop email client isnt going to work either. Because they both use IMAP in order to connect to the server and get messages. In order to help you troubleshoot this problem, wed need a bit more information from you. Such as the email address you are trying to connect with, and the mail server you are currently trying to use. If youd like to go ahead and reply to this comment with that info, we can keep that info private and try to find out for you whats wrong. It sounds like the address youre using to access your mail is incorrect, so please double check your email settings to make sure they are correct.
