I maintain an Exchange 2000 server for a small company. Users outside of the office can log onto Outlook Web Access with no problem, but users inside the office, signed on to the domain, cannot use Outlook Web Access. (They normally just use Outlook.) What do I need to do to allow inside users to get into Outlook Web Access?
Try using the local IP address instead of the Exchange server name. If you are able to connect, check your DNS setting. Make sure the DNS setting is pointing to the local server, and add the DNS entry for Outlook Web Access. Also, check your firewall. It is possible that it is preventing users from going out to the Internet and coming back up.
