I'm looking for a CalDAV, CardDAV client for Windows

I've recently been trialing FastMail as a replacement for my patchwork setup of using Gmail and Outlook.com to sync contacts, calendar, email and so on - so far it looks good.

    You'll also need to generate a one-time "App Password" from your Fastmail account settings instead of using your regular email password. This is a simple security step that Fastmail requires for syncing with external clients like this.
