We currently use Public Folders with Exchange 2010. We have a series of shared calendars throughout the organization. Some of the items posted require us to set up devices (video conferencing for example) at a certain time, but the end users who schedule these appointments aren't always the best at letting us know when it is (even though it's supposed to be several days in advance/notice). Other than the obvious way of just going out to those individual calendars multiple times a day to look, is there a way to have Exchange (or powershell, Outlook, etc) alert us via email when an event has been created? For instance if Powershell could go to the Public Folder database, search for any entries added within the last 12 hours, then email me to let me know. Even if I could set it to run once a day, each morning at 7.30 am, that would be a huge help. Thoughts?
