Well that didn't work for me! Took an hour to reset factory setting so I lost all my apps, the error STILL appears when I go into my hotmail account. I also lost all the recent updates including the calls and sms blocking app which means my two stalkers will continue to be able to hassle me. I wish someone would take responsibility for this error and sort it out once and for all!! I paid a lot of money for my 925 and I'm totally fed up of this continuing error, being given incorrect advice on how to solve it and I'm begining to wish Id stuck to my old mobile!!! This seems to be an error on several of the new Lumia models, why can't someone resolve it???!!!!
