Out of office Agent - Notified List

How does the R6 OOO Agent handle the notified list? In R5 the list was cleared each time the agent ran, and because of that, the agent was limited to running daily.

In R5 there was also a Rem’ed line of code; Appenditemvalue, which could be replaced with the replaceitemvalue that updated the notified list, is this still applicable?

I was reading some posts and it seems like agent can run more then once a day without any probs.

Is there a way to have it clear less often?
