You need to have SSL to access an Exchange server via Activesync. All you need is port 80 open.

On Exchange 2003 side we have a SSL certificate to access mails from outside and synch mobile phones. On Exchange 2007 side we have only a self signed certificate. Some migrated users can now synchronize the mobile phone although there is no SSL certificate installed on Exchange 2007. Does someone of you know how this is possible ?
