When syncing my PocketPC's calendar with Outlook 2003, I keep getting the
following error:

"The following recurring appointment cannot be written to Microsoft Outlook
due to error 80180F01. The item will be skipped."

Then it explains which recurring appointment the error is being thrown on.

I press skip but it continues to show up and an unresolved item.

What does the error mean and how can I get rid of it?

Thanks,
David
