An Outlook plugin that synchronizes events, tasks, and contacts between Microsoft Outlook and any CalDAV/CardDAV server such as Google, Nextcloud, SOGo, or iCloud. It is free, open-source software (AGPL-3.0) supporting Outlook 2007 through 2021 and Office 365 for Desktop.

Use cases

  • sync outlook calendar with nextcloud
  • two-way sync outlook with google calendar
  • sync outlook contacts with a carddav server
  • use outlook with radicale or baikal caldav server
  • replace exchange with caldav for outlook users
  • sync outlook tasks with caldav server
  • keep outlook and icloud calendar in sync

When to choose

  • you use Outlook on Windows and want to sync with a CalDAV/CardDAV server instead of Exchange
  • you want a free, open-source Outlook CalDAV plugin
  • you run Nextcloud, SOGo, Radicale, Baïkal, or similar self-hosted groupware
  • you need two-way sync of events, tasks, and contacts with broad server compatibility

When to avoid

  • you use Outlook on macOS or mobile - the plugin is Windows-only
  • you need Exchange or EWS sync rather than CalDAV/CardDAV
  • you want a standalone sync tool not tied to Outlook
  • you require a permissive license for proprietary redistribution (it is AGPL-3.0)
