Outlook CalDav Synchronizer at a glance

The plugin connects Microsoft Outlook to any CalDAV and CardDAV server and synchronizes appointments, tasks and contacts in both directions. Supported services include Nextcloud, SOGo, mailbox.org, Google and other groupware systems. This lets Outlook act as the familiar front end for self-hosted or external calendar and address management.

The add-in is maintained as open source and published in versioned editions through the public project archive. New editions add server profiles, adjust to current Outlook and .NET versions, and harden the processing of XML responses.

When updating, watch compatibility with the Outlook and .NET version in use; after installation it can be worth re-checking the synchronization profiles. In distributed environments a central rollout is recommended so that time-zone and character-set settings stay consistent and syncs run reliably.
