Scripting

Someone asked a similar question a little while ago and I don't think there is an official way to do it. The best solution I could think of is to setup a rule in Outlook that will save the attachment someplace. You would need to have a copy of Outlook running on a computer that would handle that, however.

It's not currently a feature: http://kace.uservoice.com/forums/82699-k1000/suggestions/2587560-automatically-save-scheduled-reports-to-a-network-

Thanks for the update, it seems to be the simplest way to do it.
