password dilema - domain pw change wipes out stored outlook pw

[kevinr]

We require domain members to change their network password every 90 days.
When they do so, the stored email password in outlook gets deleted and
they're prompted for it when they connect to the pop3 server that host our
email.

Our setup is 2003 Server , a single AD domain, XP SP2 workstations and MS
Office 2003.

Thanks for any help.
