There are all sorts of samples of CDO 1.21 code at www.cdolive.com/cdo5.htm.
I also had mentioned a sample for folder aging properties also located at
CDOLive.

Each folder's aging properties are stored in a hidden item in the folder (in
the HiddenMessages collection of that folder). When you are accessing the
store using cached mode you have access to the OST file and not directly to
the Exchange mailbox. The OST should synch to the mailbox at scheduled
intervals and a send/receive all usually does that synch.
