Exchange's Systemmailbox

[Moostang]

On my server (win2k server) I am running Exchange 2000 (sp1) I have a mailbox called SystemMailbox, now I realize this is probably a required mailbox, but I was wondering if someone could give me a small explanation of what it is used for, is it a redirector of some sorts?
I am just a bit concerened because I see that is has 1000+ mail items in it, and I don't know if this is something I need to clear out, and I don't know how to do it since for some reason I don't even have the option to purge that mailbox from the server.

The size of my SystemMailbox is 1,256 items using 2,609 KB. Is all of this stuff necessary?

Not knowing exactly what's making up the additional items in that mailbox above and beyond the standard schema definitions, I can't really tell you if it's all necessary. That said, things don't randomly get put into the SystemMailbox, so if it's in there it probably belongs there. Plus, 2.6mb is not a particularly large size; I would leave it as is.
