Exchange 2007 Availability service not working when connecting thru RPC over HTTPS

By maho - Posted on 04 August 2008

This was a bit tricky, getting free/busy data from he exchange server just did not work, using OWA or connecting without RPC gave me the free/busy data just as expected but when connecting over RPC outlook kept telling me that "free/busy information cound not be retrieved".
Lokking at the autodiscover settings I found that the only Availability service address being published was the internal one wich of course was the cause of my problems, so anyway solution below.

Set-WebServicesVirtualDirectory -Identity "EWS (Default Web Site)" -ExternalUrl:https://mail.external.com/EWS/Exchange.asmx -BasicAuthentication:$True

2003 FreeBusy

Having sort of the same problem. If forms based authentication is enabled on a 2003 box then the call to ?Cmd=freebusy gets intercepted and forced through the forms... which is not very nice as we need to handle a large volume of calls. Is there a way to configure a separate virtual directory that would allow for basic authentication?

Thanks :)

yes there is
