Archive Shortcut Deletion

I would point out that just removing the EV Outlook Add-in will not stop archiving.

Sure it will stop the user MANUALLY ARCHIVING, but then not clicking the Store in Vault button will do the same thing :)

Background/scheduled archiving will still take place using whatever policy is applicable to this user.

... until you disable them from archiving as you said.

Then yes, shortcut deletion is the way forward.. but remember if you change the policy, and synchronise mailboxes 'all' people targeted by the same policy will also be impacted.

A better approach might be to export their archive back to their mailbox .. or export it to PST and then simply create an Outlook Search Folder with all shortcuts in (you can do it based on message class) and delete them.
