I just switched from Iphone to Android (Huawei 4Glte)

And after setting up an exchange account In encounter 2 major issues that I cant fix.
1. It doesnt sync all subfolders
2. After re-start of the phone the checkbox for sync of mail, calender and contact is unchecked and all data is gone until I re-check and it has to download everything again.

Any idea where to start looking for a fix?
Im using the standard apps with the phone.
Im using m.outlook.com as the server
