The secret culprit behind the Windows Phone 7 phantom data issue is ... *drumroll please* ... Yahoo! Mail.

Windows Phone 7 guru Rafael Rivera confirms what insiders have been telling me for more than a week:

Scary. Yahoo is sending ~25 times as much data as it needs to. (This can also be read as: Your phone is downloading ~25 times as much data as it normally would, had you sided with another email provider.)

To workaround this, I strongly recommend Yahoo mail users reconfigure the phone to not transmit data via a cellular connection (Settings –> Cellular –> Data roaming options). As an alternative, you can set your Yahoo account to only Download new content only on manual trigger (Yahoo Mail –> Settings –> Sync Settings).

The problem is down to Yahoo’s IMAP server (winmo.imap.mail.yahoo.com) and the fact that it doesn't respond to FETCH requests correctly.

No word from Yahoo! on this yet.

Nice bit of sleuthing there Rafael  ... well done!

    How surprising since Yahoo's mail service has been so stellar in recent years, as is their customer service.

    Note the sarcasm.

  • LIES!

    This is obviously some scheme by M$ to boost the amount of data that is being used by the 3 Windows Phone 7 users in the world. The fact that they're blaming Yahoo is likely Money Boy Ballmer's fault.

    Screw him.

      I bet this is what DonnieBoy will say: "Screw M$. It's all Ballmer's fault"

  • So both Yahoo Mail users are in trouble

    So not really a platform bug is it ;-)

  • In before the haters.

    Just remember folks, before you hate, remember that the iPhone can't tell time, and Android doesn't seem to quite understand SMS.<br><br>Have a good day. :)

  • MS needs to man-up...

    ...and take responsibility for this blunder.

      Huh? Why does MS need to take any responsibility if Yahoo mis-configured its mail server? Is the server even running an MS OS? If not, you're comment would, if possible, be even less relevant.

  • Some logic to the &quot;blame Balmer&quot; argument.

    They were a step away from bankruptcy before Microsoft came into the picture, Yahoo is nothing but a sub-division of Microsoft now, and at the time the Yahoo app came out they only had maybe 100 apps in the store. I agree with James that MS needs to man up and accept some of the responsibility, not dump it solely on Yahoo.

  • This is what happens when you don't stick to &quot;standards&quot;

    I love when a company messes up and then of course it's not their fault.... Grip Of Death anyone?!?!

    "It is possible to get direct IMAP access. Yahoo! operates IMAP and secure IMAP servers (imap.mail.yahoo.com in particular), which are globally accessible. However they require a specific, non-standard IMAP command to be sent before login is done, namely: ?ID ("GUID" "1")?. It is feasible to modify an open-source e-mail client to send the ID command, and there are modified versions of Mutt and Mozilla Thunderbird available to download. Alternatively, one can connect an unmodified e-mail client through an IMAP proxy that adds the ID command. A commercial software package that accomplishes this is called 'Yahoo IMAP Connector'. Mutt-dev (1.5) works without any modifications."
