When using Outlook to lookup the free busy data for a Notes user, the free busy query fails. The EWS Web Service shows the following error in the log:
System.ServiceModel.Security.SecurityNegotiationException: The server has rejected the client credentials. ---> System.Security.Authentication.InvalidCredentialException: The server has rejected the client credentials. ---> System.ComponentModel.Win32Exception: The logon attempt failed
1.) Locate the following file on the CMN Free Busy server:
C:\Program Files (x86)\Dell\Coexistence Manager for Notes\Free Busy Connector\DominoFreeBusyService\DominoFreeBusyService.exe.config
2.) Make a backup copy of the file.
3.) Edit the original file and locate the following settings block:
<add baseAddress="net.tcp://localhost:8960/FreeBusyService" />
4.) Edit the "baseAddress" to match the string selected in the Domino Free Busy Service Endpoint in the CMN Management Console GUI.
5.) Restart the Domino Free Busy Service.
A Product Defect, TFS 441174, has been logged for this issue and is waiting for a fix in a future version of Coexistence Manager for Notes.
