Sync Calendars and Contacts with Microsoft Outlook

With the Outlook CalDav Synchronizer, Outlook users can easily sync their events, tasks and contacts between Microsoft Outlook and their Nextcloud server.

Full Outlook synchronization

The CalDAV and CardDAV plugin offers two-way sync for CalDAV calendars and tasks, CardDAV contacts and can also handle the Google native Contacts and Tasks API.

The plugin handles Outlook categories, mapping CalDAV server colors to Outlook category colors and syncing calendars and tasks to the categories. The plugin also handles timezones and recurring events with exceptions and can deal with Outlook custom properties.


The Outlook CalDav Synchronizer supports:

  • Auto discovery of calendars and address books;
  • Configurable sync time range filter;
  • Time-triggered-sync and sync changes from Outlook immediately; and it can use server settings from an Outlook IMAP account profile.

Mozilla Thunderbird

Thanks to the Mozilla Thunderbird Lightning Calendar add-in and the Cardbook Thunderbird Contacts add-in, Nextcloud Groupware integrates great into Thunderbird.
