I'm trying to setup a Calendar Overlay with Exchange on my project calendar. I can browse the OWA URL and the Exchange Web Service (.asmx) in Internet Explorer without any errors. Both URLs use https and are third-party
signed. After I inupt the URLs into the Overlay config screen and save, Sharepoint attents to retrieve the calendar information and throws the follows error: "Could not establish trust relationship for the SSL/TLS secure channel
with authority" on the calendar screen.
