Same for my test installation because of self signed certificate.
However Outlook asks only once after startup :).

I'm using (ip.addr == && (tcp.port == 443) as filter for
wireshark, see screenshot attached.

I have no such problems while erasing and reconfiguring accounts in
Outlook. Only once I was unable to synchronize, after restarting SOGo in
between without restarting Outlook. Later I found a log message in the
SOGo logs, that a port was already in use => One SOGo process got stuck
while restarting. After killing it by hand and restarting SOGo
everything was working normal again.

Unfortunately not. For the Apache configuration I have wrapped a
VirtualHost around my SOGo.conf to make sure SOGo is only reachable
using this hostname. Additionally I added a dedicated log file for
better overview.

See site configuration attached. sogo.piraten.lan.conf is permanently
redirecting to HTTPS and ssl_sogo.piraten.lan.conf is my site
configuration for SOGo. Both stored in /etc/apache2/sites-available/. If
you use the virtual host configuration you have to disable the default
configuration in /etc/apache2/conf-available/SOGo.conf

That was my suggesting with the virtual host in the previous paragraph :).
