Encryption menu option is grayed out on the client?

Question

I am trying to remove full drive encryption on a computer and have followed the various steps ( kb and forum entries ), but the Encryption menu option on the client is disabled. 
 The policy is set to allow users to enable/disable encryption, that policy has been successfully synchronized with the client, but I still can't access those option. 
 I am right-clicking the encrypted drive and that is where the Encryption option is disabled. 
 Any thoughts or suggestions would be very much appreciated!

Hi Bill, 
 
You'll need to change your Device Protection policy and set "User may decrypt volume" to "Yes". You'll also need to change "Media encryption mode" to "No encryption" so the hard drive doesn't re-encrypt once it's been decrypted.

I have worked this out now as unlike my Safeguard 7 server which mainly serves Bitlocker clients, I found the v8 server I build to require a different approach to decrypt window s7 or below clients admittedly I just followed the below pasted from a Sophos manual. The weird thing is the machine should have both policies applied at the same time I found encrypt (with allow user to decrypt volume as above) and decrypt but you must have the decrypt policy take priority by selecting no override, only then did the greyed out option become available to decrypt the drive. 
 Summary below: 
 These are the necessary steps to decrypt a drive that is protected by SafeGuard Device Encryption. 1. Edit the current encryption policy that is applied to the Client which should be decrypted so that a user has the right to decrypt volumes 2. Create a new policy and set the &ldquo;Media encryption mode&rdquo; status to &ldquo;No Encryption&rdquo; 3. Create a new SafeGuard group 4. Assign the decryption policy at domain level, activate it only for the group and set the priority to 1 as well as no override. 5. Assign every machine that should be decrypted to this SafeGuard group (Note: make sure the encryption policy still applies to the machine if you remove it your option will still be greyed out!)
