By default the Messaging application does not sync the sent items folder.  Therefore, you may notice that your sent items folder is empty. Here is how you "fix" it :-

Pocket PC :-

  • Menu -> Tools -> Manage Folders
  • Select "Sent Items"
  • Press OK
  • Sync

Smartphone :-

  • Menu -> Folders
  • Menu -> Manage Folders
  • Select "Sent Items"
  • Press Sync
  • Press Done
  • Sync
