I had issues with calendar sync as the new BESAdmin here and after several days working with Blackberry support I found my solution. My files were the same version all along but somewhere along the line the files did not register correctly.

1) Make sure these 2 files are the correct version on both Exchange and BES Server.

2) Unregister these 2 files from the BES Server Registry and Re-register through a DOS command prompt window.

3) Reboot BES and see if it helps. The Log files on the BES will also show types of errors you are getting to some detail.

NOTE:***There are many things that can cause this issue...
