Cingular Treo 750 running WM5.0, pOutlook, and ActiveSync connecting to Mail2Web Exchange server.

I have a special folder called Saved Items. It holds preformatted messages that I occasionally forward to clients to save typing time. Lately, I have noticed the files are all visible in the Mail2Web window but the Treo pOutlook version of the folder only shows the files with dates in the last couple of weeks. Does anyone know where the setting is to be able to see all of the files, regardless of age?
