Outlook CalDav Synchronizer is a free Outlook plugin that’s in charge of synchronizing agendas and calendars between your Outlook account to other business and productivity programs like Google, SOGo, Nextcloud, and CalDAV. For CardDAVE, you will find that there is two-way synchronization for calendars, tasks, and contacts. This open-source program supports one of the earliest to the latest Microsoft Office programs so you can test it in other operating systems.

What is CalDAV synchronizer?

Outlook CalDAV is the only open-source CalDAV and CardDave plugin. It offers two-way sync for CalDAV calendars and tasks, CardDAVE contacts, as well as Google Native Contacts and Tasks API. The app will take charge of organizing your Outlook categories and mapping your CalDAV server colors to Outlook category colors so calendars and tasks are synchronized. It will also handle timezones and recurring events, including Outlook custom properties. 

The plugin offers SSL/TLS support, which allows you to sign certificates and authenticate client certificates. Those who are tech-savvy can manually configure the proxy for basic authentication proxies. This will allow you to automatically sync prior and future commitments in your calendar and address books from multiple profiles. This includes Google Native Contacts API and Google Tasklists. You can also map Outlook Distribution Lists to contact groups and CalDAV server colors to Outlook category colors. 

Its other advanced capabilities are the WebDAV Collection Sync (RFC 6578), the ability to use server settings from Outlook IMAP/POP3 account profile,  and the ability to map Windows to standard IANA/Olson timezones, and map Outlook formatted RTFBody to HTML description. These features take out the guesswork in syncing; you will receive reports of the last sync runs and status through push notifications in your system tray. 

Never miss a schedule 

Outlook CalDAV Synchronizer is a suitable productivity tool for those using multiple programs to manage their schedules. While the list of programs it can sync with is limited, they are available for personal and professional use. Its support for two-way synchronization creates the same schedule on every software so you can always see your full schedule at all times; however, experienced users will get the most out of this program as it can be reformatted through coding.
