Huawei Nexus 6P :: Exchange Server Screenlock

Whenever i set up the exchange mail account, i have to set up a pin or password to unlock my phone. When i want to change back the pin / password to a pattern, i cant and it says: "disabled by administrator encryption policy or credential storage"

Normally the reply on this post would be, your company has set up these minimum requirements for security purposes and you cant put up the mail/agenda unless you accept the terms of the company.

The weird thing is, my company doesn't`t require any security measures at all. If you want to swipe to unlock, you can (well, other people can ).
