I have been using outlook for my work emails as well as 2 apps from DTNA (daimler) for work. Up until about a week ago they were all working properly then suddenly outlook stopped syncing emails or it will work one day for a few hours and then stop again yet all my calendar and contacts still sync. Also my 2 DTNA apps will no longer recognize my username and pass yet i can go to my computer and log in no problem.. The company uses apple phones and non of those phones are having issues only android devices?
