# Mac OS X: Add contact service (CardDAV) in Contacts.app

Important Notes

- SOGo provides EAS (Exchange ActiveSync) support, but not EWS (Exchange Web Service).
- Outlook 2013 for Windows works well with EAS.
- Below mobile devices works well with EAS, they will sync mails, calendars, contacts, tasks, memos/notes.
  - BlackBerry 10 devices
  - iOS devices (iPad, iPhone). Tested with iOS 8.1.3.
  - Android devices. Tested with OS v4.0.
- Apple Mail.app, and Outlook for Mac support EWS. But not EAS.
- Outlook 2010 for Windows supports MAPI.
- iRedMail doesn't integrate OpenChange and Samba4 for native MAPI support, so SOGo groupware in iRedMail doesn't provide full support for Microsoft Outlook clients, Mac OS X Mail.app and all iOS devices, don't try to add your mail account as an `Exchange` account in these mail clients. You have to add separate POP3/IMAP account, caldav/carddav account instead.

## Requirements

- iRedMail-0.9.0 or later releases is required.
- To use contact service (CardDAV protocol), you must choose to install SOGo groupware during iRedMail installation.

## Step-by-step configuration

1: Open application `System Preferences`:

2: Click `Internet Accounts`:

3: on right panel, click `Add Other Account` at the bottom

4: choose `Add a CardDAV account` in popup window

5: Choose `Advanced` in the `Account Type` drop-down menu, then fill up the form with your server address and email account credential

- Server Address: `your server name`. For example, `mail.iredmail.org`.
