We have BES 4.0.18 and Exchange 2003 sp1, since we went to BES version 4 we cannot sync from blackberry to Outlook in the calendar. We can sync from Outlook to Blackberry but not the other way.

I have re-registered cdo.dll, I have rebooted the server, ai have alsogone through a number of steps, re setting up the mail client, new mapi,Blackberry articel KB-03650.

I have logged a call with Vodafone but they have not got back to me, can someone help please?

We have sp1 on the BES Server and all 3 hotfixes applied.

We just need to get the bi-directional wireless calendar working, wireless setting is set on the Blackberry in the calendar and the bi-directional settings are set on the BES.

Please help
