Hello everyone,
I have a problem with the installation of the Blackberry Enterprise Server Express with Zimbra connector for Blackberry enterprice server.

I've seen other posts that signaled this problem but have not found a definitive guide for my case:
Zimbra Collaboration Suite 7.1.1
zimbra proxy in DMZ
zimbra mailboxes on LAN

bes express server in LAN (in the AD domain)

The installation went well until I asked "Microsoft Exchange Server"!!

The answer was that not recognizes.

Can anyone help me?
