Enable message prepopulation for activated Blackberry smartphone users

If you try and re-activate a user on your Blackberry Enteprise Server with the same smartphone the Blackberry server will not prepopulate messages during the enteprise activation stage. Let’s say that a user accidently lost the phone and you managed to delete it through the server. If the user finds the same phone and you try to activate it on the server for the same user, old messages for this user will not be transfered on the phone during the enteprise activation stage.
You can change this behavior with a little registry tweak on the Blackberry Enteprise Server.

1. On the BlackBerry Enterprise Server, click Start > Run and type regedit.
2. For a 32-bit Windows Server®, go to HKEY_LOCAL_MACHINESOFTWAREResearch In MotionBlackBerry Enterprise Server
   For a 64-bit Windows Server®, go to HKEY_LOCAL_MACHINESOFTWAREWow6432NodeResearch In MotionBlackBerry Enterprise Server
