Has anyone gotten reliable access and/or integration to MS Exchange calendar data with any DNN event/calendar related module? At least twice a year we have a fairly serious request from someone to have their organization's calendar - homed and curated in Exchange - to be made visible in some way via DNN, either public, extranet, or intranet style. Is there some other way to skin this cat? Does Exchange have any way available to expose the calendar data (XML, RSS, JSON, etc.) in a way that could be periodically retrieved, consumed, and integrated?
