PowerPoint 2010 autorecover puts users over profile limit
Problem
The AutoRecover feature in PowerPoint 2010 is constantly causing users' profiles to exceed the disk space limit set by administrators.
Changing the AutoRecover file location from the default (C:\users\user_name\appdata\roaming\microsoft\powerpoint) to another folder outside the profile (e.g. C:\temp\micosoft\autorecover\powerpoint) doesn't help; PowerPoint still puts its autorecover files in the default location, in the user's profile.
Solution/Workaround
As of January 2012, there's no way to force PowerPoint to put its autorecover files in an alternate location. The workaround is to turn off the AutoRecover feature. This Microsoft page explains how.
