The app was working fine until recently, then a dialogue box appeared while trying to opne the mailbox: "Reset OWA. You need to reset OWA. Resetting will delete any information that hasn't been sent to the server." Clicking on RESET causes the app to crash, clicking on CANCEL simply delays the process and the error dialogue returns. I've tried uninstalling the app and reinstalling, but to no avail, it still constantly crashes. Any thoughts on how to resolve the issue?
