Outlook 2003 Cached Exchange Mode Sychronization

I am running in "Cached Exchange Mode" and I have to
continuously click send/receive before it synchronizes my
local copy with the server. It seems not to sense that
the local and server copies are out of synch. In one
microsoft document, it suggested that I go to 'File' and
click 'Cached Exchange Mode' and then click 'Full
Message.' When I go to 'File,' Cached Exchange Mode is
not one of the options. (Note that the "Use Cached
Exchange Mode" has a check beside it in the-Mail accounts
page. (Tools--e-mail accounts--View or change existing
e-mail account--Change--Use Cached Exchange Mode).

Once I get the local copy in-synch (by repeatedly
clicking send/receive), the online/offline functions work
perfectly.
