cdo.dll calendar issues

I am receiving {%user%} CDOCalendar::~CDOCalendar() – Exception handled

After some research I have found that the issue could be from the cdo.dll not matching up correctly.

Here is what I am showing: (keep in mind BES is on a seperate server)

Cdo.dll v. 6.5.6944.0
Bes v.
Exch Sys Manager v. 6.5.6944.0

Cdo.dll v. 6.5.7638.2
Exch Sys Manager v. 6.5.7638.1

right now I'm kind of at a stand still on not sure which way to go.

For this type of setup you need the CDO.dll to be the need to install Microsoft Exchange Server 2003 Service Pack 2 on your BES server to bring the CDO.dll up to date and my guess all the post SP2 Exchange patches.  

I have run into this a few times in my travels.

Your BES Box does not have any service packs installed and your exchange server is at SP2

Here you go

Microsoft Exchange Server  2003                     6.5.6944                  
Microsoft Exchange Server  2003 SP1                 6.5.7226                
Microsoft Exchange Server  2003 SP2                 6.5.7638                
Microsoft Exchange Server  2003 post-SP2            6.5.7653.33              
Microsoft Exchange Server  2003 post-SP2            6.5.7654.4

thanks.  That is what I was thinking that the BES wasn't updated, but I couldn't find anything to show it.  That chart you posted is perfect.

I'll take a look and get the update rolling
