Today my boss asked what it would take to create a link on our corporate website that would allow users to access their email via Outlook Web Access. Currently I allow a handful of users rights to logon via OWA to get their email by using a public address. Some of the problems that I have experienced with OWA is that you have to use a Micrsoft browser for it to work. Also, if a user has a cable modem service such as AT&T's @home, a proxy setting is forced and a registered DLL has to unregistered to allow connectivity. Would I need a VPN configured on my network to allow users to access to OWA via a corporate web link? What are the possible security risks involved with implementing this? Thanks.
