Syn your calendar (several persons/devices) without google calendar

Get owncloud, choose a cloud service (or use owncloud to create your own cloud server at home) that can be connected with owncloud (I selected ocloud, it has an app also); follow the manual (Sogo Connector plugin is for contacts, so not needed) to set up the calendar for thunderbird (its using CalDAV so should also work for outlook) and use an app that can use CalDAV (I am using OneCalendar); just create several calendars (e.g.: Work, Private,…) that can be synced between (several) thunderbirds and several android/iphone mobile devices

 

Access outlook exchange with thunderbird

Use DavMail gateway; really helpful if your work place insists on outlook but you want to use a mail program on your home computer
