Hi Everybody,

I currently experience the following strange behavior with my Outlook Connector:

I am at a remote office location where my internet access is almost direct (static offical IP address / no NAT / "probably" no Firewall)

The Outlook connector is not able to connect to my Mailserver but HTTPS Webaccess works fine. I thought that the KOC is also just using SSL but it seems that some other protocol is involved when connection to the KMS - and this seems to get filtered/dropped somewhere.

It is not a configuration problem as KOC works fine when I am using my Hotel WIFI.

Does someone have any idea what could cause such a problem.

Thanks,
Marco

Just because it works from a hotel, and not the office doesn't necessarily mean it's not a configuration issue. There are a few things that could cause it to work in one location, but not another. Some could be specific to the network, some could be specific to your computer.

Did you use the same address in the KOC server name field that you use to connect to webmail? Do you have the SSL checkbox enabled? Are your DNS servers inside or outside of your network? What happens when you try to connect to webmail without using SSL? Does the remote office connect via a VPN tunnel to the main office?

I would double check the "probably" no firewall, as a firewall can cause these types of problems. I've also never seen a remote office connected to the internet without some sort of protection. It might be basic and simple, it might be built into your router/modem, it might be installed on the PCs themselves, but there's always something to protect the machines.

No NAT? You only have one computer at the remote office?

In both, https:webmail and KOC I use mail mailservers name (resolution via dns works I also tried it via hosts file) I also tried just the ip address - of course I do get a certificate error then. SSL is checked in KOC. http:webmail also works.

The reason why I am not using NAT is because we are using 6 IP addresses that are passed-by our firewall in order to get unfiltered and unsecured access to the internet. It is mainly used for testing. My Laptop is currently using one of these 6 IP addresses. Our router, that I am connected to right now, is not having any access lists or firewalls enabled.

As I said i find it very strange as I've never had any problems like that with KOC before - and the very same KOC configuration worked without any problems on many different networks in the past.
