>Yes, I figured out that specific ID are reserved for base folders. But, what about the ones I created. Those are the ones that interest me. I need to scan thru all the messages for a folder named "Michel Fournier", for example.

For nondefault folder, you can use the Folders collection.

loInbox=loNS.GetDefaultFolder(ccOlFolderInbox)
oMFfolder = loInbox.Folders("Michel Fournier")
