OWA freezes on my iPhone as soon as I try to run it. All I get is this message: http://sdrv.ms/13TcXRv (I was wondering if it has to do with special characters in the log in process. I'm still clueless though.)

I have added my Outlook account to my phone, I use it with the default iOS mail app everyday.

iPhone 5, iOS 6.1.4.

Thanks in advance for any hint.
