Disable Outlook 2007 AutoArchiving

I've disabled Outlook archiving in group policy using the offce 2007 adm templates. However, there are a lot of PC's (about 200) that appear to have archive.pst files between 2mb and 100MB with last modified date's as the current.

Does disabling autoarchiving in group policy not disable the existing archiving Outlook users?

If not, how can I stop their archiving besides manually visiting each workstation?

Every time a PST is opened, it changes.  It doesn't matter if nothing is actually changed, archived, or done in the PST...it still shows "changed".  You have disabled auto-archiving (you can check by going to one of your Outlook clients and seeing if "auto-archive" is available or grayed out), so it shouldn't take place, but each archive is still open in Outlook for the user to access.

Users can still manually archive their items if they choose to.  In order to stop the use of archive files in any way, you can disable the ability to use PST files.  Let me know if you want to know how to disable the use of PST's.

Thanks for the information; that makes sense.

If you have information on the disabling of pst files, I will glady take that and see if I could implement that in my environment.
There is a set of GPO settings available with the Office 2007 ADM template:
Microsoft Office Outlook 2007/Miscellaneous/PST Settings

Within that there is a setting:
Prevent users from adding PSTs to Outlook profiles and/or prevent using Sharing-Exclusive PSTs

Set that to enabled.
