Outlook 2003 - Pocket PC Duplicate appointments

Hi-

I just upgraded from Office 2000 to Office 2003 and have found that Outlook
2003 works so much better with my Pocket PC running Windows Mobile 2003.

Unfortunately, though, when synchronizing my PPC to my notebook, I somehow
duplicated my old appointments twice, so that I have three entries for
everything from 2001 to last month. How can I have this culled out? I HAVE
seen sometimes, when synching, that a window will ask me if I want to delete
duplicate entries, but I haven't seen that come up lately and I can't seem
to locate any way in the menus to delete the extra entries. Oh-and the
triplicates are on both the PPC and the notebook!

Any suggestions?

Thanks!

David
