Here's our problem, users who want to change their password trough OWA get this error "The password you entered doesn't meet the minimum security requirements.", even if users are respecting the minimum security requirements.
With these settings, we have the error:
Enforced password history 1 passwords remembered Maximum password age 185 days Minimum password age 1 day Minimum password length 7 characters Password must meet complexity requirements enabled
With these test settings, we don't have an error:
Enforced password history not defined Maximum password age not defined Minimum password age not defined Minimum password length not defined Password must meet complexity requirements not defined
People can change their password but there is no more security!
Just changing one parameter of the GPO for example "Enforced password history", brings back this error.
Here's our server configuration :
Windows Server 2008 R2 Exchange Server 2010 Version: 14.00.0722.000
If anybody has a clue it would very helpful !
