Can't access Hotmail via Outlook Express with Websense enabled



Article ID: KB7104 KB Last Updated: 24 Aug 2010Version: 4.0
Can't access Hotmail via Outlook Express with Websense enabled


  • Hotmail
  • Websense
  • Outlook Express configured using Hotmail Account

Symptoms & Errors:

  • Hotmail access fails
  • If websense is disabled I can get to the hotmail account


The HTTP method (PROPFIND HTTP) used by Outlook Express to access Hotmail is not currently supported in the Websense configuration.

The workaround is ... on the policy associated with Hotmail access, set the "application" parameter to "ignore".  In testing this workaround, a policy was created specifying the parameters to permit HTTP traffic (with url-filtering enabled for Websense functionality).  When "ignore" was set for the application parameter Hotmail access was permitted.  All other HTTP traffic was handled by Websense as expected.

The "ignore" option, which appears near the end of the list of application choices, instructs the NetScreen device to ignore the application type typically associated with a predefined service and port number.  Using the "ignore" option instructs the NetScreen device not to scan the packet payload and can prevent the NetScreen device from attempting to parse one type of traffic when it is actually another type - such as the case with LDAP and H.323 traffic, both of which use TCP port 389.
