The Sumatra Utilities for Exchange 2007 are now available for download.
Keep in mind, they won't just insert holidays for the 2010 calendar year, they'll also let you:
- Check for broken meetings in your conference rooms
- Gracefully remove terminated user meetings
- Extract resource use data you can then analyze in a spreadsheet (not full ResourceWatch but it gives you easy access to data that was hard to get before)
- And if you want to start using them to develop your own applications (we've got one business school that's done that and another evaluating), we can do that as well.
