Lollipop: override security policies (specifically lock screen/Exchange/Office 365) When I used Android 4.4 (KitKat) on my Nexus 5 I could ignore certain security policies such as a requirement to have a PIN code to unlock the lock screen. After upgrading to Lollipop and the move of Exchange e-mail from the separate E-Mail application to GMail this is no longer possible. Are there any workarounds? E.g., when I used Android 2, there was a hacked version of the E-mail app apk floating around that told the server it enforced the security policies but in fact ignored them.

I have seen a lot of similar questions, e.g., 

How can I override the Device Administrator security policy so that I can disable the lock screen?

ActiveSync/Exchange security policy

etc but they are all for older versions of Android.

(For everyone that is gonna whine about security policies in my employment agreement, I demanded, and it got approved, a clause that guaranteed me to have root privilegies or equivalent on all my personal IT equipment. My manager accepts this but the IT department is in a different universe. Taking this issue/the IT department to court for breach of contractual agreement is, for obvious reasons, not an option.)
Try the Mail Wise app. It bypasses Exchange security, but you won't be able to use the Gmail app.
