User Name: (user name)
Logon Type: 3
Logon Process: Advapi

The two likely scenarios when the failure occurs is:
Cause A: The User Account does not exist in the Active Directory/Windows Security realm configuration.
Cause B: The password is invalid. This may be obscured by the fact that the user will have authenticated using the MailEnable credentials rather than the Windows Authentication (as a result of the Windows Authentication failure).
Cause A: Ensure the account exists within Windows Active directory.Cause B: Ensure the password for the account is correct.
