Mail app on 10 keeps telling me my account settings are out of date, I know they are not as I have updated several times, they work for 30 minutes, then I get the same message, they work fine on my phone , with the same settings, I had no issues until your last update to the Mail app, it has been a horrible experience since,fix it, it is not a fault on my end as it works every where else, its not a fault on my account settings as they worked fine prior to last up date, I am not dumb, work in IT and have for over 20 years, you have stuffed the app
