Hi everybody,

we have Kerio Connect 9.2.3 installed in a Windows environment (Server 2016 - Windows 7 Client)
On the Client side we use Outlook 2013 an Kerio Connector for Outlook

When the user tries to send or forward a message to another user on the Kerio server outlook shows an NDR saying:

"Your email message could not be delivered to the following addresses:
<unknown> (failed)"

and an attachment text file:
"Reporting-MTA: dns; W7PC07
Arrival-Date: 20170718T071804Z

Action: failed
Status: 5.0.0
Diagnostic-Code:"

W7PC07 is the computer name

I tried reinstalling the outlook connector and cleaning users caches local and on the server, no success

Any help?

Thanks

Andreas

Officially, Kerio Connect is only supported on Windows Server 2016 from version 9.2.4 on.

Nevertheless, sending emails should work. Does this work if you try from the Kerio Web Client?

Yes, sending mails from web frontend works, that´s why i´d guess the problem is somewhere with the outlook connector

OK, I would upgrade to 9.2.4 and then check if it still happens.

If so, I would open a support case with Kerio/GFI.

upgraded to 9.2.4, but that was not the solution
but i found out that outlook was my point of failure, not kerio.
Somehow there were old entries in the old nk2-Files I importet from the old Exchange Environment. Had to clean up contact entries now it works

Thanks for reading
