I see this time and time again. A user is having problems with his device so after some basic troubleshooting you decide to wipe and reactivate the device ...

You don't remove the user from the BES because you don't want to have to setup Groups / IT Policy / Software Configuration ... and you don't want to lose Automatic Wireless Backup data ... but the user wants his messages back.

Well, as we all know, there is no way to guarantee you'll get all of your messages...
