Hey,

I installed the official Outlook.com application on my Sony Xperia U, running android 4.0.4.
It worked perfectly over WiFi but can't sync over 3G.

After searching the forum for answers, I found a workaround on http://answers.microsoft.com/en-us/windowslive/forum/mail-sync/outlookcom-app-on-android-phone-will-only-work/978dd5e2-d24c-4f3b-9bdb-547f021679db but I can't apply it on my device since my APN settings are locked.

How can I fix this?
