Outlook 2000 rules in error.

Hi, All,
I am having trouble with my Outlook 2000.
Several rules running right now. One of them causes error. Outlook displays “Rules in error”
“Can not move the items to the folder.”

I tried moving a single message to the folder, but did not work. same message of “Can’t move the item” showed up.

Is there a maximum number of unread or read messages in a folder?

I am using Win 2k & Office 2K Premium with service packs.

Thanks,
