Hi,
We have federation services enabled and organisation relationships setup - all which are working OK. But when a user tries to look at the free/busy information for a user in a remote organisation we get the following error in the application log:
4001 -
Process Microsoft.Exchange.InfoWorker.Common.Delayed`1[System.String]: <user, Remote>SMTP:remoteuser@remote.com failed. Exception returned is Microsoft.Exchange.InfoWorker.Common.Availability.AutoDiscoverFailedException: Autodiscover failed for e-mail address <user, Remote>SMTP:remoteuser@remote.com with exception Microsoft.Exchange.InfoWorker.Common.Availability.AutoDiscoverFailedException: The response from the Autodiscover service at 'https://remotecasserver/autodiscover/autodiscover.svc' failed due to an error in user setting 'ExternalEwsUrl'. Error message: User setting 'ExternalEwsUrl' is not available. .

. Name of the server where exception originated: LOCALCASSERVER. This event may occur when Availability Service cannot discover an Availability Service in the remote forest.
I have checked WSSecurity is set to True for the webservice and autodiscover. I can open the autodiscover address and logon and the cert is trusted.
Not sure what is wrong?
