Microsoft: Yahoo Mail Responsible for Windows Phone 7 Data Drain
Microsoft suggested an "inefficiency" between Yahoo Mail and the Windows Phone Mail client is causing Windows Phone 7's unexplained data drain for some users.Microsoft is blaming Yahoo Mail for a "data-drain" bug affecting a small subset of Windows Phone 7 devices. For weeks, the company had been investigating complaints of smartphones devouring users' data, even when not running applications or cruising the Web. Some users reported that this unexplained consumption totaled between 30MB and 50MB within a 24-hour period.
On Jan. 20, Microsoft claimed it had located the cause behind the data drain: an application created by an unnamed third party, which the company apparently made aware of the issue. Almost immediately, rumors leaked across the blogosphere that Yahoo Mail was the application in question.
2. Choose "Settings" from the application list.
3. Choose "E-mail & accounts."

5. Click on the setting under "Download new content."
6. Select a less frequent setting. If you are using the default setting (every 2 hours), change this setting to "manually."
7. Click on the setting under "Download e-mail from."
8. Select a shorter time range. If you are using the default setting (the last 2 weeks), change this setting to "the last 7 days." Microsoft's statement to Thurrott also highlighted a separate issue with Exchange ActiveSync e-mail synchronization, which will apparently be fixed "in a near-term end-user update from Microsoft." In the meantime, users can apparently solve the issue by deleting any e-mail that appears "stuck" in the outbox. Microsoft plans on issuing a series of software updates that will tweak the smartphones for better performance and introduce a missing cut-and-paste feature. Currently available on GSM-based networks such as AT&T and T-Mobile, Windows Phone 7 is scheduled to appear on CDMA (Code Division Multiple Access) networks such as Sprint and Verizon before the second half of 2011. Microsoft hopes the smartphones' unique user interface, which consolidates Web content and applications into a series of subject-specific Hubs, will allow it to regain market share against fierce competitors such as the Apple iPhone and the growing family of Google Android devices.
