the client is already discontinued. That’s exactly the message you quoted.
It currently still works and breaking the api it uses would also mean breaking the connection to a lot of other components in the Kopano stack. So it will probably stay around for a while, but no guarantees on that.
to me it looks like a vhost conf problem, perhaps try to disable ssl first for debugging and just running it on vcard standard prort 8843 …
also we use centos and i dont know the paths for shared mapi library … for us: /usr/share/kopano/php/
No carddav support as per today. Some people say it’s possible to get Sabre-zarafa running, but it does not for me, yet.
So you’re stuck with contacts on Macs. Something that really annoys me.
Some of our users have a lot of shared mailboxes to open and therefore is it isn’t usefull to see 8 different inboxes.
what do you mean here with “different mailboxes”? through the shared folder functionality currently the calendar will be included in you own mailbox and not as a dedicated store (even though that is also an often requested feature that we are currently investigating).
