Hi EugeneR,
This is now solved, thank you, so I'll summarise:
I left two important details - Exchange 2003 is installed on the BES server, and MS's MAPI/CDO v1.2.1 can't be installed on a system where Exchange 2003 is installed. MS provides a CDO package without MAPI and I had installed this.
The other important thing was that Exchange's System Management Tools were installed, which is, as the ZCB guide clearly says, not supported with ZCB. My mistake.
Outlook 2003 has never been installed on this box.
The solution was to uninstall CDO, Outlook 2007, and ZCB - as you suggested - and also the Exchange System Management Tools.
I then reinstalled Outlook 2007, and then ZCB. I noticed the 'Mail' applet in control panel was missing. I ran Outlook once, and the Mail applet appeared.
From this point on - without installing CDO - everything worked fine, and users could be provisioned.
Hurrah!
Thanks,
Kevin |
