name of security certificate is invalid when i open up outlook 2007 with exchange 2010

When i get the error the certificate that is shown is a mail. certificate.   when i go onto my server the certificate that is shown from go daddy is remote.            Would that be the cause of the issue?

Did you use the Microsoft New Exchange Certificate Wizard (see right) to generate a list of SANs that you should include

Subject Alternative Names required:
Include both the external and internal fully-qualified domain names of your Exchange CAS server(s). For example, owa.domain.com and owa.internaldomain.com).
If you are using autodiscover, make sure you include an entry for autodiscover (the autodiscover service uses autodiscover.domain.com by default).
If you use the same URL for OWA, Activesync, Outlook Anywhere, or any other service on the Exchange 2007 server and only have one CAS server, you do not need to take any extra steps. However, if this is not the case, review the following lines.
If you are using different URLs, make sure to include entries for those as well.
If you are using more than one CAS server, make sure to include the internal fully-qualified domain name of every CAS server that is involved.
If you are using any CAS servers, make sure to include the internal fully-qualified domain name of every CAS server involved

outlook 2007 does not understand SAN certificates and only will read the first Subject Name so you need this hotfix http://support.microsoft.com/?kbid=968858&wa=wsignin1.0
