In fact, Windows Phone Secrets, through its own investigation, had already determined that Yahoo! Mail was sending about 25x as much data as it needed to the phone; the Microsoft statement issued later in the day simply confirmed that result.
Microsoft said that they and Yahoo! have identified a fix, which will be rolled out in the "coming weeks." In the meantime, Microsoft suggested the following workaround:
- On the Start screen of Windows Phone 7, click on the arrow at the top right
- Choose “Settings” from the app list
- Choose “email & accounts”
- Choose “Yahoo! Mail”
- Click on the setting under “Download new content”
- Select a less frequent setting. If you are using the default setting (every 2 hours), change this setting to ‘manually’
- Click on the setting under “Download email from”
- Select a shorter time range. If you are using the default setting (the last 2 weeks), change this setting to ‘the last 7 days’
Just when that "near-term end user update" comes is a question. Microsoft was supposed to release its first big update to Windows Phone in January, and it is now February. Additionally, a recent report by NPD showed that Windows Phone was actually outsold by the creaky Windows Mobile in the U.S. during Q4 2010, not a good sign.
