An Update for Yahoo! Mail Windows Phone Users
For Yahoo! Mail users on Windows Phone, we are aware of a Windows Phone synchronization inefficiency with Yahoo! Mail, which could result in larger than expected data usage for a small percentage of users. We are currently working with Microsoft to help them resolve the issue. In the meantime, here’s a link to Microsoft’s support page explaining how you can change your Windows Phone settings to reduce the frequency of your phone updating Yahoo! Mail. Please click on this link and follow the steps outlined. We recognize this might be an inconvenience, and we will provide an update soon.
