This confused me until I figured it out so hopefully it'll help someone else.
When you have CalDav window popping up on your ipad/iphone, ipod, do this..
How to set up CalDAV:
Go to the "Settings" page on your mobile device.
Select the Mail, Contacts, Calendars option.
Select the Add Account option.
Select the Other option.
Select the CalDAV option.
Enter all the requested information including:
- Your Yahoo! Mail email address and password
- Enter this information in the Server box: https://caldav. calendar .yahoo.com(you have to type this into where it says server info, of course without the spaces in between)
Tap OK or follow any additional steps your mobile device requests.
If you still can't figure it out from these instructions then leave me a message and I'll walk you through it.
