Owncloud 8.x was ok (see article below), but Owncloud 9.0 is broken beyond repair (at least calendar and contacts).Use baikal for calendar and contacts sync on Blackberry 10. I have a Blackberry Z10 which runs Blackberry OS 10 as operating System.Keep in mind that baikal cannot to calendar delegates (i share my calendar readonly with another user). Owncloud 9.0 ships with more or less functional calendar and contact plugins that are full of bugs and have half the features as the plugins known from version 8.x. My tablet running android 4.x and few people with android smartphones and i Phones sync against that owncloud instance too.
Today is a great day for our Doodle users because they’re now able to integrate their Doodle events into and Office 365 calendars.
i Cloud & Outlook Calendar issues are at i Cloud and Outlook Calendar Sync Issues and Contact issues are at i Cloud and Outlook Contact Sync Issues.
i Cloud 2 users should check Outlook and i Cloud 2: What you need to know and Outlook and i Cloud: default data files Users with POP3 accounts seem to have the most problems (but could benefit the most from i Cloud), since the data is local to one computer.
