As of this morning, when users open Outlook to get their emails, there is a Security popup window that states:

Information you exchange with this site cannot be viewed or changed by others. However, there is a problem with the site's security certificate.
The security certificate has expired or is not yet valid

Exchange uses an SSL certificate just like a website would for https. Is the certificate expired?

In the Exchange Management Console, select "Server Configuration" from the left hand tree. You should have a "Exchange Certificates" list. You can double click on them to open and view when they expire.

What certificate is this related to your Exchagne cert for CAS? Open the cert and see if it has actually expired. If it has then this is why you are getting this message. It might also be a 3rd party plug-in that requires a cert. To check this open Outlook in safemode (outlook.exe /safe). If your cert has expired you may need to create a new CSR and generate a new certificate from your 3rd party provider.

There is no "Exchange Certificates" list. This is a Exchange 2007

Thanks

Exchange uses certs in order to work peroperly. You should have certs installed on your Exchange servers directly or on your load balancer (if you are using one).

You can use the get-exchangecertificate (on the local exchange box) to get the certs that are installed on the machine.

As stated if they are expired you will be required to generate a new CSR (on your Exchange server) and submit it to your SSL provider.

The Exchange Certificates list in the Management Console is for Exchange 2010. As others have said, you have to use the get-exchangecertificate via command line to view in Exchange 2007.
