I have recently added a certificate to an EV server to allow Outlook Anywhere clients toaccess archived messages.
We have assigned the certificate ev.company.com to IIS and changed over the setting to change EV to use SSL all seemed to go well with external access but internal clients had a problem with a certificate mismatch in that the EV site is ev.internal.company.com.
I can prove the certificate mismatch by opening archive explorer, approving the mismatch and then going back to opening archived messages without a problem.
Any input would be appreciated.
