Hi Andrew,

can you clarify when the connection fails?
1) network connection
2) authentication
3) post-authentication


* What repositories are you using?
* How did you install and configure Kolab?


* Can your clients resolve your servers' FQDN and actually reach the server 
(via ping)?
* IMAP, SMTP and HTTP ports are opened on the firewall?


Some checks you could perform:
* 'telnet your.mailserver.org imap' works and you're getting a CAPABILITY 
response?
* STARTTLS is working (assuming you are using TLS connections)?
  E.g.: 'openssl s_client -host my.mailhost.org -port 143 -starttls imap
* Can you access https://your.mailhost.org/Microsoft-Server-ActiveSync/ ?
