I have set up 3 new e-mail accounts but i am getting an error message on receiving on 2 of these accounts.


The message is:-


Internet Security Warning


The server you are connected to is using a security certificate that could not be verified.


The certificate's CN name does not match the passed value.


Do you want to continue using this service


It gives you the option to click yes to continue.  All 3 accounts are set up the same way the distribution certificate has been installed so not sure what the problem is?

This can be caused by several things.


Doublecheck the settings for the two accounts you are having issues with -- some require just the username (before the @), some require the full email address. Check the email providers documentation on what is required for this field.


Make sure the time, date and timezone are set correctly on the computer. Large time differences between the computer and the mail server can result in failure to make a secure connection.


Doublecheck the incoming and outgoing server addresses in Outlook. Make sure the server addresses are entered correctly and that you are using the correct ports. Because you are relying on certificates, your email providers' servers are probably NOT using the default ports for SMTP, POP and/or IMAP, but some other port instead. Your email providers should have documentation on how to set this up.


Also make sure your Windows Updates are up to date. Microsoft pushes out the most recent CA certificates using Updates.
