Microsoft is confirming officially that -- as at least two bloggers reported in January -- that Yahoo Mail is causing the data leakage problems that some Windows Phone 7 users have encountered.

Up until today, Microsoft officials declined to name the application which was causing the problems. On January 31, company officials admitted it was Yahoo Mail.

A fix to the problem -- which "can result in larger than expected data usage for a very small percentage of users" -- will be delivered "in the coming weeks," Microsoft told Windows Phone Secrets author Paul Thurrott. Until then, Microsoft is providing a workaround to alleviate the data-leak problem.

Microsoft officials also acknowledged there is a problem with the Microsoft Exchange ActiveSync (EAS) e-mail synchronization protocol that may be affecting a number of Windows Phone 7 users. Affected email services include anything using that protocol, including Outlook and Gmail. The immediate workaround for the problem is to delete any mail that appears "stuck" in the outbox. Microsoft officials said this problem will be fixed in a "near-term end user update from Microsoft."

Microsoft still has yet to release its first update for Windows Phone 7 (the "No Do" release that was originally known as the "January update"). We've heard for a while that it is "coming soon."

On January 31, researchers at NPD found that Windows Phone 7 captured two percent of the U.S. smartphone market in the fourth quarter of 2010.Android is now at 53 percent of the U.S. smartphone market, according to NPD. Maybe the Microsoft folks should take a look at my colleague Larry Dignan's ideas for jump-starting WP7 sales...

WP7 began shipping in Europe in October 2010 and the U.S. (from AT&T and T-Mobile only) in November 2010. Microsoft and its CDMA phone partners Verizon and Sprint have said there will be more phones coming on those carriers some time this year, but have continued to decline to provide a ship-target date.

As a Verizon customer, I'm trying to hold out to see what Windows Phone 7 options Verizon will be offering. A representative from that carrier recently tried to convince me to upgrade to an iPhone. When I asked about Windows Phone 7, it seemed that rep had never heard of it.... Guess "Android's Law" -- the increasingly rapid pace at which phone providers can churn out new Android phones -- doesn't apply so far at all to the Windows Phone.

Update: Yahoo provided a statement at the end of the day on February 1 that acknowledged the problem, but added that Microsoft's software also was to blame, at least in part. From the Yahoo statement I received from a spokesperson via e-mail:

“Yahoo! Mail is widely available on tens of millions of mobile phones, including those running on Apple iOS, Android, Nokia Symbian, and RIM. The issue on the Windows Phones is specific to how Microsoft chose to implement IMAP for Yahoo! Mail and does not impact Yahoo! Mail on these other mobile devices.  Yahoo! has offered to provide Microsoft a near-term solution for the implementation they chose, and is encouraging Microsoft to change to a standard way of integrating with Yahoo! Mail, which would result in a permanent fix.”

  • Yahoo! is a non-issue, EAS is the red meat...

    One of the biggest selling points of Windows Phone 7 to the enterprise is Exchange integration and how WP7 is supposed to do that better than anything else on the market. Getting a FAIL on that right out of the gate doesn't bode well.

    • EAS is not the issue here

      @jasonp@... The problem is how Yahoo pushed mail to WP7 and other devices, NOT EAS.

      iPhones have the same issue too if you read the support forums.

      And WP7 has the best Exchange sync since I had my Blackberry. It's far superior to the crappy EAS experience I used to have with my iPhone.

        This could explain my having to change password all the time. Ever since I got my WM7 and use Yahoo Mail, I've been getting emails from myself that I haven't sent. I change password and I'm good for a week or so then it starts all over. Darn you Yahoo, Darn you! I have NO problems with Hotmail or Gmail emails.

        @dazzlingd See perception is the issue here. WP7 is expected, being that it's MS, to have superior Exchange sync than anybody else and if they are anything less than superior at it then the perception is failure.

    This will upset a lot of people because they can't blame Microsoft for this like they have been doing.

    • I thought it was MicroHoo

      @Loverock Davidson ... they don't have a good enough relationship to integrate their mail product with WP7?
      The avalanche of money Microsoft is blowing on this thing, they couldn't actually *test* this?

        @HollywoodDog
        I hope you realize that Microsoft and Yahoo are two separate entities who's only working relationship is advertising. Given that information, why would they have a relationship on a phone OS?

      @Loverock Davidson Really, nobody can blame MS for this anymore? Guess you missed the statement from Yahoo that was included in the article....<br><br>[i]Yahoo!

    Glad to hear MS has identified the issue and fixing it quickly.

    Mary Jo, Sprint reps know about WP7 phones and are excited about getting them. Verizon reps have probably been told to push IPhones due to new agreement they have. I've had a few Sprint repstell me WP7 phones were worth waiting for.

    • Are the Sprint reps talking dates?

      Even ballpark dates would be way more useful than "some time in 2011"... Any word from those you know?

      Thanks. MJ

      @smehaffie [i]Verizon reps have probably been told to push IPhones due to new agreement they have. [/i]

      I was just talking with somebody yesterday about Verizon and the iPhone. We had both noticed that at most a month ago we were seeing a lot of Verizon Android ads but since the announcement that are almost exclusively iPhone ads.

    FWIW, it appears that Verizon shares absolutely zero information about future plans with their sales reps. My guess is that Verizon's ship date for Phone 7 will be on Engadget before they tell their reps about it.

    That said, I'm right there with Mary-Jo, waiting for Verizon and wishing I knew when they'll start offering Windows Phone 7.

  • Small Impact

    At least this will only affect about 20,000 users. 2,000,000 phones sold to providers x 1% actually sold (given) to users x 1% using yahoo mail!
