Hi,We are using exchange 2007 and in my outlook 2007 I am getting a security alert of certficiate as per the following :"Information you exchange with this site cannot be viewed or changed by other. However, there is a problem with site'ssecurity certificateThe security certificate is from a trusted certifying authorityThe security certificate date is validThe name on the security certificate is invalid or doesnot match the name of the siteDo you want to proceed"See, I know the name of my exchange server and certificate is not same, that is why this error is coming, so I installed this certificate in my pc when I get this alert, but still it is appearing.Please advise how to resolve this issueJinesh Kumar

Hi, The Certificate Name should be same as the URL which Outlook needs to access. For example, the Outlook needs to access the https://server.domain.com/OAB to download OAB files. The Certificate Name (Subject Alternative Name or Subject Name) needs to include server.domain.com. Install the certificate on client is not helpful to solve the issue. For more information regarding the certificate in Exchange 2007, you can refer to following article: Certificate Use in Exchange Server 2007 http://technet.microsoft.com/en-us/library/bb851505.aspx Mike
