Tell sched validate "your canonical name"
Check Notes log or Admin console for any errors
Tell sched list "your canonical name"
Check Notes log or Admin console for any errors.
Check entries listed to make sure no entry has been inadvertently created that repeats 24 hours a day.
Check for repeat entries that are created too far into the future e.g 2090. Known to mess up the busytime [I think there is a Technote too].
Check your busytime one year from now - still appearing busy? If not, then chances are the erroneous entry is before that date.
You can also delete your entry in the busytime or clubusy.nsf and then run tell sched validate. Your busytime entry will be recreated.
