User unable to reset password from Exchange 2010 OWA

Users may face error when trying to reset their mailbox password from OWA. The error reported will be “The password you entered doesn’t meet the minimum security requirements“, even-though you have used a complex password.


This can be resolved by making a small modification in your Domain Controller’s Default Domain Policy. By default, the ‘Minimum Password Age‘ policy will be set for 1 days. This should be changed to 0 days instead. Minimum password age actually determines the period of time (in days) that a password must be used before the user can change it.

Steps are:-

  1. Launch Group Policy Management [gpmc.msc]
  2. Select the Default Domain Policy and edit the same to obtain the Group Policy Management Editor
  3. Navigate to Computer Configuration -> Policies -> Windows Settings ->  Security Settings -> Account Policy -> Password Policy -> Minimum password age


  1. Change the number of days to 0 and save the settings
  2. Update the group policy

Now check and confirm from OWA that the password reset is successful.
