INTRODUCTION
This article describes the View Certificate button that has been added to the Internet Security Warning dialog box. This dialog box may appear when you connect to an Internet Message Access Protocol version 4 (IMAP4) server over a Secure Sockets Layer (SSL) connection by using Microsoft Office Outlook 2007.



MORE INFORMATION
When you try to connect to an IMAP4 server over an SSL connection by using Outlook, you may receive an error message that resembles the following error message:

Internet Security Warning

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

A certificate chain processed, but terminated in a root certificate which is not trusted by the trust provider.

Do you want to continue using this server?

If you are using Microsoft Office Outlook 2003 or an earlier version of Outlook, this error message may not include enough information to help you determine whether to click Yes or to click No in the error message. In Outlook 2007, this dialog box has been updated to include a View Certificate button. When you click View Certificate, a Certificate dialog box appears. You can view additional details about the certificate in this dialog box. The Certificate dialog box contains the following three tabs:
 * The General tab: Information about errors or about problems that occurred with the certificate appears on this tab.
 * The Details tab: Detailed information about the certificate appears on this tab.
 * The Certification Path tab: The full path of the certificate appears on this tab. The certification path represents a sequence, or &quot;chain&quot;, of certificates that leads to the Certification Authority from which the certificate originates. You can use the certification path to help determine whether to trust the validity of the certificate that is used to help provide security for the IMAP4 session.

You can use the information on these tabs to help determine whether you want to trust the server from which you received the certificate. For example, you receive the error message that is mentioned in the &quot;Symptoms&quot; section. When you click View Certificate, the following information may appear on the General tab:

Certificate Information

This CA Root certificate is not trusted. To enable trust, install this certificate in the Trusted Root Certification Authorities store.

Issued to: mail.contoso.com

Issued by: ca.contoso.com

Value from:  to

When you click the Certification Path tab, the following information may appear:

Certification path

mail.contoso.com

Certificate status

The CA Root certificate is not trusted because it is not in the Trusted Root Certification Authorities store.

Note The information that appears under Certificate status resembles the information that appears on the General tab.

When you review the information on these tabs, you can determine whether the certificate is valid but not currently trusted by the computer. You can also determine whether the certificate is invalid or has expired.
