Kopano Server connects with Zarafa client, but not Kopano OL extension.

Hello

I have a kopano test server running.
I wanna test if i can connect with zarafa client AND kopano OL.

Zarafa works fine i can connect to the server with outlook.
Kopano OL extension doesnt work though.

Outlook fails to connect saying something like:
"Cannot login to Exchange ActiveSync-E-Mail-Server (EAS): The server wasnt found " (I translated this to Englisch, original message might differ slightly.)

I can ping the server and it does answer.
Also it works perfectly fine using Zarafa.

If anything, i expected it the other way around, with Kopano working and Zarafa not working.
Kopano should be stable i guess?

///////////////////////////////////////////////////////////////////////////////////////////////////
Specs bellow:

Server:
Centos7
kopano-server 8.6.2

Client:
Win7 - 32bit
Outlook 2016
Zarafa-client 7.2.6
KopanoOL extension 1.6

Kopano doenst help with any usefull error log files.
I tried to enable as much logging as possible in /etc/kopano/server.cfg file.

#log_level = 3

#log_timestamp = yes

# Buffer logging in what sized blocks. 0 for line-buffered (syslog-style).

# Audit loglevel (0=no logging, 1=full logging)
audit_log_level = 1

# Audit log timestamp - prefix each log line with timestamp in 'file' logging mode
audit_log_timestamp = 1

Any ideas how i can search for the cause of that issue?

Hi @pfl ,

is there anything logged in you webserver logs when outlook tries to connect? Have you setup an ssl certificate for the z-push vhost? have you done any ssl hardening on that vhost?

Hi @fbartels,
Thx, for replying.

Let me explain further.

• No hardening happened.
• No z-push installed.
• Thus no ssl for z-push.

The server is only running in a local network.
And we only need to confirm that we can connect to Kopano-Server using outlook2016 with kopanoOL client.

I think for this we dont need z-push at all?
Or is that a dependency for Kopano to run properly?

@pfl said in Kopano Server connects with Zarafa client, but not Kopano OL extension.:

It is at least a dependency for Outlook 2013 and above (as they now connect through activesync, which is provided by z-push)

Hey @fbartels ,
Sry my head was somwhere else…
z-push is installed xD

But i didn’t confugre ssl yet.
I’m gonna do that and see if it helps.

It works now.
Seems like ssl is mandatory for it to work.

Thx @fbartels : )
