Interesting to see that Microsoft Outlook + Exchange is changing their freebusy access model toward using a web service (whatever this may mean) instead of relying on public folder synchronization.
Unfortunately, I'm having a hard time finding the specification for this web service. But apparently, it allows for some kind of point to point cross domain freebusy queries.
Although it is not officially part of the product, we do have a freebusy gateway allowing Sun Calendar users to see the free busy information of Exchange users. We've tried to prototype the opposite (Exchange users accessing Sun Calendar users freebusy info) for some time but the lack of API on the Exchange side made us postpone this project.
This new web service kind of changes our perspective although I'm not sure it is for the best. Even if the web service is published, we may also have to deal with autodiscovery mechanism.
That said, most of the customers migrating off Exchange to our Comms Suite usually run pretty old versions of Exchange. So we may not hear about this web service for long.
