Deleting a No End Date Meeting

Hi All

I just setup a meeting on Axigen Mail Server version 8.1.2. unfortunatly i did not click on the dot to select end after 2 occurences. i managed to reject the meeting on the other applicants but as i set it up on my system the meeting is now there forever. i have tryed to edit to remove the meeting and it only edits that day. like wise if i delete the meeting it removes it only for the day selected.

Does anyone know how to remove all instances of this meeting?
