The Intra2net Groupware Client must be able to access the Intra2net system via IMAP/IMAPS, SMTP and HTTP/HTTPS from the Outlook process. Therefore, the corresponding ports must be opened in the firewall of the client.

If the firewall is running in learning mode, please note that HTTP/HTTPS is only required for calendar changes, requests of free/busy lists, and configuration of forwarding and absence automation.
