CALDAV "unauthorized" Mac Server 10.10

We have Mac server yosemite 10.10.

When I connecting from Thunderbird (Lightning) or from iPhone or from android Phone with plugin, calendar work great. But from emClient no, emClient asking for credentials and then write “Unauthorized”. What can I do with this?

I use this url: __uids__ /FC452466-06D8-4BCA-9BAC-3FB1601F9EF2/calendar/

This url work fine on all other clients.
I can access this url over browser.

Thank you


We have Mac Server 4.0 in Yosemite 10.10.

We use this URL in CalDav / Cardav in EM Client:

and is working.

Sorry,  a question.

In Thunderbird, you can connect you to Addresbook Server?
do the connection via CardDAV? How?

Best Regards,


Hi Tomas, can you try to update your client to this release and possibly adjust the server address to the above suggestion and check if the issue persists?

Thank you,

Thank you Paul,

This version work fine with my http address.

And https work too fine

I tried this:


sogo connector

Hi Tomas, glad it works, please make sure to let us know if you come across any other issues or questions about the application, we’ll be happy to help.

Thank you,

OK, last question, how can I access from emClient to shared calendar and addressbook from macserver?

With above url I can connect to my calendar and addressbook.

Thank you.

You should be able to setup calendar sharing on your server or if enabled under Access Control of the calendar.
To open access control, right click the calendar folder and select Properties > Access Control.

However these options may not be available for your server.

Hope this helps,
