In the middle of last month users were reporting their Windows Mobile Phone 7 handset seemed to be crunching through data even when connected to Wi-Fi networks. Microsoft investigated the issue and discovered the cause towards the end of January and has now released details of the third party app responsible. Yahoo! Mail.
The discovery was made by a coder by the name of “Rafael Rivera,” who having been a victim of the data leak himself decided to take apart a series of IMAP packets that were sent to and from his Windows 7 Phone.
After doing a few calculations he discovered that the Yahoo Mail app was using 25 times more data than it required. Micorsoft have now confirmed his findings and pointed the finger directly at Yahoo! Mail. with the inefficiency existing in the synchronization of email between the Windows Mobile Phone 7 Mail client and Yahoo! Mail one. However the problem is thought ot have only affected a small percentage of users.
Yahoo! and Microsoft are now working together to fix the problem which should be ready within the next couple of weeks. But if you are experiencing the problems you could try the following steps to correct the issue.
