Certificate warning

This warning indicates the server name does not match the name in your account settings.

The easiest fix is to change the server name. You need to choose to install the certificate or use the servers’ IP address or server name instead of using mail.yourservername.com  in your Outlook settings

 
To get your mail server's IP address:

1.   Type cmd on the Start menu to open a Command Prompt.

2.   Type ping mail.yourservername.com to find your IP address and the hosts server name.




3.   If the server name in the ping results matches the name on the certificate, use it as the mail server name in Outlook.

4.   If the name is different, ping the server name used in the certificate. If the IP address matches your mail server's IP address use it as the mail server name in Outlook.
