Correct iCal errors, display problems, and buttons that do not work in the Yahoo calendar

If you have trouble adding your Yahoo Calendar to a mobile device or an application such as Apple Calendar or Mozilla Lightning, it is usually related to the iCal address. Most feature problems, such as buttons that don't work or display errors, can be resolved with general browser maintenance.

Unsupported devices

If your device does not support CalDAV (iCal), you can access your Yahoo Calendar through a mobile browser at https://m.yahoo.com/.
