Hi there,
thanks for your quick reply.
The BESAdmin is Domain User and member of the needed Exchange groups.
The DWORD "Ignore No PF" is added
I've installed the CDO 1.2.1 on the BES server. I don't have Outlook on this server, I've already made that error

This is a reinstalled server
Also there are no MMC on the server.
So I belive I've got the basics coverd
Hope you can guide me in the correct direction.
Thanks
Droopy
