Security options grayed out I have my mobile phone (Samsung Galaxy S2) running on ICS. Recently I activated Microsoft Exchnage ActiveSync to connect to my corporate email. It disabled all the security options like 'Pattern Unlock'. I hated it, and removed my microsoft active exchange account from the phone, but these options are still disabled. How do I get it enabled?
As a last ditch effort, you could try this:


Use Titanium Backup to backup all your Apps + Data.
Reset the phone to factory defaults.
Restore all apps and data except for Activesync.


This will definitely fix your issues.  Question is, "Is it worth the effort?"
