I have been using the outlook application to my galaxy s3 for a year now with no problems . But for the last two weeks now I  cant connect to my account if I use 3G internen.It only sync and connect to internet when I am on a WI-FI. I push to sync and it doesnt respond and appears the message " Last connected at ..." I removed my account and added it again but nothing. I even uninstalled the app but still  nothing. Could anyone help me to sort this out??
