I want to use the calendar overlays to show an aggregate view of multiple conference room calendars on a single sharepoint 2010 foundation webpart. The calendars are resource calendars held on an SBS 2003 server. Is this possible? I get
a 404 error if I try to navigate to https://myowaserver.contoso.com/EWS/exchange.asmx with IE. If I try the calendar I get the following error:
Could not establish trust relationship for the SSL/TLS secure channel with authority 'myowaserver.contoso.com'
These are the entries in the overlay calendar:
is SBS 2003 not supported?
