Cancel multiple instances of a recurring meeting

I have a recurring meeting set up on my calendar. Outlook 2007 will not
allow me to cancel multiple occurrences. I can cancel the first one just
fine. I open the second occurrence I want to cancel, I click "send
cancellation" and then I get a message that says "Changes to the meeting
cannot be saved. The meeting has been updated by another person. Close and
reopen the meeting and then make your updates."

I close and reopen and it still won't let me send the cancellation. I'm
editing the specific occurence not the entire series. I have to clsoe
Outlook and reopen it to send the second cancellation. Outlook 2003 would
let you do this but 2007 always gives me problems.
