Microsoft Exchange Outlook Web Access (MS OWA) Other solutions Configuration The remote host seems to be running Microsoft Exchange Outlook Web Access. This is a web-based interface for Microsoft Exchange Outlook. An attacker may gain additional information about the target or elevated privileges. The server should be deactivated or de-installed if not necessary. To make it harder to find the server the daemon could be configured to listen at another port (e.g. 8081). Try to prevent unwanted connection attempts by filtering traffic with firewalling. Alternation of the application banner can confuse an attacker and let him determine the wrong software.
