Exchange - Internet Accounts - Contacts, Calendar, Reminders not working

I have set up Exchaneg account to sync Contacts, Reminders, Notes and Mail.

Mail and Notes is working fine(actually Mail I had to setup to poll every 1 minute).


Contacts:

Exchange account visible but contacts not synced.

Yellow ! showing:

This operation coudn't be completed.
(SOAPWebServicesErrorDomain error -1.)


Log is flooded with:

19/06/15 07:42:30,315 Contacts[1050]: Stream 0x7f9f47050dc0 is sending an event before being opened


Reminders, Calendar

Exchange account not showing up at all, only icloud.

I tried deleting and recreating account.

Any ideas how to debug this?

Here's a few more for ya... Tons of these, Not much you can do about it. Also happens in Mail and Notes.

6/19/15 00:00:43.394 Mail[12768]: Stream 0x7fcb603db020 is sending an event before being opened

6/19/15 00:28:42.133 Notes[46518]: Stream 0x7ffec80a9800 is sending an event before being opened


Regarding This operation coudn't be completed, what version of Exchange? Do you have acess to the Exchange Server logs? Curious what you're seeing on the server side. Have you done a check via https://testconnectivity.microsoft.com?

All of a sudden my 99% of my Contacts disappeared in the Contacts app but I can find them in Spotlight.
