Error: The password you entered doesn't meet minimum security requirements.

Using Exchange 2013 Standard on premise with Active Directory on another server. I keep getting the same error when I use the change password function: The password you entered doesn't meet minimum security requirements. Am I missing a configuration.
I ran this command on the Exchange Server: Get-OwaVirtualDirectory |fl *pass*
Got this: ChangePasswordEnabled : True

I also ran this command on the server and set the GPO password settings way down to get this to work:  net accounts

C:\Windows\system32>net accounts
 Force user logoff how long after time expires?:       Never
 Minimum password age (days):                          30
 Maximum password age (days):                          180
 Minimum password length:                              1
 Length of password history maintained:                24
 The command completed successfully.

The password complexity is disabled.

I entered this password: a1cs6nx.2T   and still got the "The password you entered doesn't meet minimum security requirements."  Doesn't make sense.

What is next?
