4.0 ice cream sandwich - 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?

Answer

As a last ditch effort, you could try this:

1. Use Titanium Backup to backup all your Apps + Data.


2. Reset the phone to factory defaults.


3. Restore all apps and data except for Activesync.

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