Why can't I "save an item" (an event) to my calendar for Dec09?

[Andregas]

Where can I find the rules set for advance calendar-ing? I can find where
archiving is set, but why can I post an event in October bt not December of
this year.

Exactly what happens when you try? What version of Outlook are you using?
