It appears that Outlook Anywhere is an all or nothing proposition. Internal clients are connecting to automatically to OA and cannot be turned off just internally. Want them to have access externally. Internally we are getting Cert errors because we only have a cert for mail.domain.com. Is the best solution to purchase another cert for "servername.domain.local" and adding autodiscover to it as well? Let me know if there are any other workarounds.
