No success. I Disabled all firewall rules (enabled for subnet globally all tcp/udp/icmp ports) on firewall appliance and also on PC's I'm testing it with.
Also further tests showed that is not an outlook specific problem for me, also thunderbird shows same behaviour. If I turn TLS in mailclient on - mails in preview get displayed If I turn TLS in mailclient off - mails in preview get not displayed (also opening mail by doubleclick does not work), but login itself send & receive and show index of mails works. This happens only with IMAP. With POP3 witz/without TLS all working. Any idea? Any additionl info needed?

Try disabling all of them to see if it works then.
