| | same problem on my 7250
I experienced the same problem on my device. Tried most of the suggestions on this forum but ended up doing a handheld wipe and an enterprise activation.
I found that everytime I plug in my bb to my PC, my desktop(cmime), desktop(cical) and desktop(sync) settings would change. I am set up on BES but everytime I plug in my bb, the service book settings change to settings on the desktop manager. I have reinstalled the DM several times ensuring I configure it for sync / work thru BES. This did not help.
Besdides never plugging in my bb to my PC, I do not seem to know how to prevent this from happening. Any help would be appreciated.
