Yahoo!® offers several services like a web portal, a search engine, social media ... Also it offers CalDAV and CardDAV access to your calendars and address book.

Important note: As of 2012-01-18 Yahoo!'s CalDAV and CardDAV servers seem to be almost completely broken. Most requests return errors. For some users it still works, others can't sync any more. At present, I consider Yahoo! as incompatible with CalDAV-Sync and CardDAV-Sync. These issues affect users of other CalDAV and CardDAV clients too (e.g. many Apple users or even Yahoo!'s Android app "Yahoo! Mail" can't sync contacts for many users).

Setup

CalDAV-Sync

• Server: caldav.calendar.yahoo.com

if you get authentication errors try: caldav.calendar.yahoo.com/dav

• use SSL: leave ticked, it won't work otherwise
• Username: your Yahoo-ID (i.e. your email address at yahoo, if your email address ends with @yahoo.com enter just the name part)
• Password: your Yahoo-Password

CardDAV-Sync

Please see known issues below.

• Server: carddav.address.yahoo.com
• use SSL: leave ticked, it won't work otherwise
• Username: your Yahoo-ID (i.e. your email address at yahoo, if your email address ends with @yahoo.com enter just the name part)
• Password: your Yahoo-Password

known issues

authentication issues

Although Yahoo! encourages you to use a safe password and include non-alphanumerical characters their sync servers have problems to authenticate your with certain characters in your password.

Here is a list of characters you should avoid in your password if you want to sync to Yahoo!:

• "
• <
• >
• +
• &

Characters that appear to be safe are:

•  !
• $
• @
•  %
• ,

Update: As it turned out it's not just certain characters that do not work. Some users can't authenticate even with alphanumeric passwords.

server errors

As of 2012-05-09 Yahoo's server seem completely broken! It's almost impossible to get a valid response from the servers above. The error codes vary from 401 and 404 to 502, 503, 504 or the connections just times out. Please note that this is not a bug in CardDAV-Sync or CalDAV-Sync. This is a server issue!

Update (2012-11-19): Currently this is more an issue with CardDAV than with CalDAV. In CalDAV-Sync you may not be able to add an account. Just retry later in that case. Also you may get an error notification from time to time (with an error code of 400 or something from 500 to 504). You can safely ignore that errors. The app retries 10 times to sync in case of an error, but sometimes even the 10th attempt results in an error. The next sync will probably work well.

In CardDAV-Sync the retry-approach doesn't work. For some users every attempt to sync returns an error code 500. Unfortunately it's impossible to sync in that case. Note that not only CardDAV-Sync is affected, OSX users see that issue too (see Error when try to sync Yahoo account with Contacts app and Mac address book sync with yahoo contacts does not work in OS X 10.8. ...).

Some users from France reported authentication problems. Please try the following URLs in that case:

CalDAV-Sync

caldav.calendar.yahoo.com/principals/users/

or

caldav.calendar.yahoo.com/principals/users/<your Yahoo! ID>/

CardDAV-Sync

carddav.address.yahoo.com/principals/users/

or

carddav.address.yahoo.com/principals/users/<your Yahoo! ID>/

Please let me know which one works for you!
