We are using Blackberry 5.0.3 with Exchange 2003 SP2. One of the user got a new blackberry device ( he was using old BB device) & end user team has configured his BB device as per process. As emails were not sync up properly, End user team, reactivate his account by wipe the device. Now everything is fine, except users not getting old emails, even day before the device configured.
I have gone through the below link, but is there any other way to sync his old email to bb device.
