EV7: shortcut deletion doesn't work

Hi everybody,

I want to migrate archives from an EV2007 environment to a new EV8 environment without using 3rd party tools. The two environments are not connected to each other. So I want to export to PST with deleting shotcuts first.

I created a new provisioning group in EV2007 to which I connected a policy which deletes my shortcuts after 1 day and it also deletes the orphaned shortcuts. In priority this new policy is above the already existing provisioning group. Membership of this new provisioning group is through an Active Directory Group. The provisioning group which is already present has as a target the whole Exchange organization and a policy connected to it which doesn't delete any shortcuts.

When I run the archive task, it doesn't delete my shortcuts whith the proper time set to (I even set my site schedule to this time), delete the shortcuts, I can see that the delete shortcut event shows up in the event shower telling "Start to check the shortcuts on the Exchange system <my exchange servername>."

The logfile of the shortcut deletion shows my users beging processed even with the shortcut deletion policy mentioned, but no shortcuts are deleted.
Does anyone has any clue why it doesn't work? I have no error messages in my event viewer.

Any help is much appreciated.
