Background: we have multiple HubCAS servers. One had a self signed certificate (it was not use for OWA) that needed to be renewed. I ran "newexcahgnecertificate" to generate a new one. I verifed the certificate was present on the server. I then deleted the out of date certificate. I checked the server and found the certificate was not updating properly. I then restarted the server.
Ater the restart I got several notices that Outlook Webservices on this sever failed. Some users could no longer get any Free/busy information when they used scheduling assistant for a new meeting, only slashed lines. I then shut down the server as I did not have time to troubleshoot it then.
Problem:Now the users are still not able to get any free/busy information even with the one CAS shut down. They did not move to one of the two other CAS servers we have in our environment. Even after a PC reboot their Outlook client is still not finding one of the availble CAS servers.
With our all 2007 environment (see details below), I expect to be able to use the Availability service on the CAS servers but some Outlook clients are not functioning properly.
Any thoughts how to get these Outlook clients to find one of the available CAS servers to get the free busy information?
Environment: Exchagne 2007 SP1 servers on Win 2008, Clients are all Outlook 2007.
