I upgraded one of our Microsoft Exchange 2010 servers to Exchange 2010 Service Pack 2. After the upgrade one of the users complained that they now had to create a pin or password  on their phones’ lock screens. Although I think this is a good idea for security purposes, this company didn’t want this hassle. This is how you disable the Exchange ActiveSync Mailbox policy from requiring a device password or pin .

Step One: Open Exchange Management Console

Step Two: Expand Organization Configuration > Client Access

Step Three: Click Exchange ActiveSync Mailbox Polices tab and open the default policy.

Step Four: Click on the Password tab and uncheck Require Password. Apply your settings.

These changes will automatically take affect across all of the devices.
