Delete single instance of appointment 1 minute after it is due.

I'm trying to write a macro to help manage my calendar in outlook.

Whenever i have an instance of a recurring appointment that contains the word '0day' in the subject line, i need it to be automatically deleted from my calendar so only the first reminder occurs and i do not need to intervene to stop the reminder replaying for these specific appointments.

I presume i would simply have nested if statements?
if '0day' in subject
if 'schedule time' < 'present time'
delete this instance of the appointment

I'm more familiar with excel where i have the macro recorder to get me started.

Suggestions?
