The TraitTool was used to configure the BlackBerry Enterprise Server to use a specific Microsoft Exchange Client Access Server for handling EWS requests. The EWSCASURL has an incorrect address.
  1. On the BlackBerry Enterprise Server, browse to C:\Research In Motion\BlackBerry Enterprise Server 5.0.x\bundle0000\tools (Where x indicates the service pack and 0000 indicates the bundle number)
  2. Make sure that the TraitTool.exe is present
  3. Open a Command Prompt:

    For Windows Server 2003: Click Start > Run and type
    For Windows Server 2008: Click Start > and type cmd in the search field and press Ctrl+Shift+Enter to elevate permissions

  4. Navigate to the directory containing the TraitTool (i.e. cd C:\Research In Motion\BlackBerry Enterprise Server 5.0.3\bundle0033\tools)
  5. Clear all EWS settings using the following commands:

    traittool -server <Server Name> -trait EWSEnable -erase
    traittool -global -trait EWSEnable -erase
    traittool -global -trait EWSCASURL -erase

  6. Re-enable EWS and point to the correct CAS URL using the following commands:

    traittool -server <Server Name> -trait EWSEnable -set true
    traittool.exe -server <Server Name> -trait EWSCASURL -set https://<Client Access FQDN>/ews/exchange.asmx
