I'm looking for real world experiences with using managed folders (other than the standard default folders). How are you organizing your folders - by retention period (i.e. 4 years), by department, or some other method? Also, I'd be interested to hear about any pain points you may have had when rolling out custom folders. We're currently using retention periods on the standard folders today in Exchange 2007 but are investigating setting up custom managed folders and let users have some control over which emails need to be retained. Thanks in advance!
