[freakency]

Just to help some other folks, I finally figured out the problem with my setup.

Some of my users get calendar sync problem, (entries not showing up in BB) but not all my users.

Mixed devices : 9000, 9800 same problems.

Deleted user's profile and created back, reinstall os, updated os to lastest one. checking every log files but I was'nt able to figure it out.

Updated to BES to the last SP and last MR.

We're running exchange 2003 and 2010, and we moved those users under 2010 just in case.

I finally figured out that BES 5.0 is trying to use the Web portion of the BES and if he is not successful, he then try to use the COD file. But in our configuration, the web portion of the mail server is not in use.

So I forced my BES to use the CDP.DLL by disabling Exchange Web Services onto the BES.

And from now on, everything is fine !

Sorry folks for my poor english...
