Configure CardDAV and CalDAV for eM Client

This article applies to recent versions of SmarterMail Enterprise. View articles for SmarterMail 16.x and earlier.
CardDAV and CalDAV are extensions of the WebDAV protocol and can be used to sync your SmarterMail contacts and calendar with eM Client. 

NOTE: If you already have an IMAP account set up in eM Client, but want to add CalDAV and/or CardDAV accounts for calendars and/or contacts, the BEST thing to do is to remove your IMAP account and re-add it using eM Client's automated setup. That way, your account will be added using all supported protocols. Setting up accounts individually can lead to issues down the road. (E.g., Odd behaviors when sending meeting requests.) See the following article for a more efficient way of configuring your account: IMAP and WebDAV for eM Client.
Follow these steps to configure CardDAV and CalDAV in eM Client:
  1. Within eM Client go to the Tools menu and click Accounts then New account...
  2. Expand the Calendar section, choose CalDAV as the connection type, then click Next.
    • For the 'Account address URL' you'll want to log in to webmail with your account information and go to Settings > Account. On the WebDAV card you'll find the URL required for any calDAV or cardDAV connections. Copy that and paste it into this field. By default, it will be in this format:
    • Fill in the "User name" with your full email address, and also input your account password.
  3. Make any necessary modifications to the account's display name to be used within eM Client and click Next. Change it to something like "Work Calendar" or "Personal Calendar" -- whatever helps describe the calendar so you know what it is.
  4. Click Finish to complete the configuration.
NOTE: With an active license -- either for the Free Edition or the Pro Edition -- eM Client will automatically sync contacts using CardDAV when a CalDAV connection is made (and vice versa). Therefore, you should only need to complete these steps once.

This does not work. In SmarterMail up to version 13, it worked using the path . In SmarterMail 14 this no longer works. Using Mozilla Lightning and others. The previous article on how to sync with Thunderbird lightning has been removed -- BOOOO HISSSSS.

If these steps are not working to connect to eM Client for SM 14, please contact our support team for troubleshooting. They can help you to complete the connection.

this does not provide detail on how to sync ONLY the calendar. When adding the CalDav connection, both the calendar and contacts will appear in em client but what if you only need one (CALENDAR or CONTACTS). clarification needs to be provide to sync only ONE. In addition to this, clarification needs to be provide for adding an account that has shared calendars attached to it with permission.

Please see the red NOTE in the article: eM Client will sync both when using either CardDAV or CalDAV. That is the way they have, apparently, designed eM Client to work with a webDAV protocol.
