We are migrating from exchange 2003 sp2 to exchange 2007 SP3. Several folders are having their contents randomly disappear. users Will look in the folders and they will be completely empty. there appears to be no real pattern to the problem. Deleted Items retention is set to 30 days but when I look in deleted Items in PFDAV it shows nothing under deleted contents. The age limit is not set on any of the folders so the items should never age out. We have had this happen on about 8 of our public folders and is causing a lot of concern cause these folders generally have several thousand messages. Please help!
