I have used this solution (disable reminders) to 'band aid' another issue;
About 476 reminders (all contacts) pop up and cannot be removed from the
reminder list. I tried dismissing single reminders, all reminders, opening
individual contacts and clearing flags/reminders, marked them 'completed',
all to no avail. This issue was in the 2007 pst file, so I brought the
problem along when I imported into ost/exchange. The contacts may have
been
sync'd with a PDA in the past and with outlook 2003. Calendar items are
not
an issue.
Running scanpst or scanost have not worked.

allows
you to disable the display of the Reminder and turn off the reminder
notification sound.
that's for Outlook 2007 - might be similar for other versions.

in my version.
